Hmm, that URL is returning something different now :(
The line numbers are all out with reference to the current trunk, even though 
the files haven't changed recently. Do you have anything odd in your tree?

The call stack is interesting (by which I mean, 'weird'). Start here:

nsContainerFrame::ReflowChild(nsContainerFrame * const 0x0012a2b4, nsIFrame * 
0x01dbbdc8, nsIPresContext * 0x01dc03c0, nsHTMLReflowMetrics & {...}, const 
nsHTMLReflowState & {...}, int 0, int 0, unsigned int 0, unsigned int & 0) line 
966

nsIFrame * aKidFrame is 0x01dbbdc8, which looks ok.

We then do:
939   aKidFrame->WillReflow(aPresContext);
940 
941   if (0 == (aFlags & NS_FRAME_NO_MOVE_FRAME)) {
942     aKidFrame->SetPosition(nsPoint(aX, aY));
943   }
944 
945   if (0 == (aFlags & NS_FRAME_NO_MOVE_VIEW)) {
946     PositionFrameView(aPresContext, aKidFrame);
947   }
948 
949   // Reflow the child frame
950   result = aKidFrame->Reflow(aPresContext, aDesiredSize, aReflowState,
951                              aStatus);

Which gets to:

nsTableCellFrame::Reflow(nsTableCellFrame * const 0x00000000, nsIPresContext * 
0x01dc03c0, nsHTMLReflowMetrics & {...}, const nsHTMLReflowState & {...}, 
unsigned int & 0) line 892

Where 'this' (aKidFrame from ReflowChild, as a nsTableCellFrame *) is null, 
eventually causing the crash. Presumably, aKidFrame->WillReflow succeeds 
because the implementation is on nsFrame.
> Do you have anything odd in your tree?

A while back I tested roc's w3c opacity patch, but since then I thought I
cleaned my tree up.  CVS checkout showed no M or C, so that leads me to believe
my tree is OK.  Should I delete it and start clean anyway?
> Should I delete it and start clean anyway?

If you have a testcase (and the time), sure.

Can you still reproduce this? If so, could you attach a reduced testcase before 
you clean your tree? (maybe not a *minimal* testcase, but certainly not 
something that depends upon external ad servers).

That way, we can at least confirm that the problem is resolved (or not).
Attached file Reduced testcase (obsolete) — 
This is about as small as I can make it.  Remove the google search, it works. 
Remove the flash object, and it works.	Remove the <map>, and it works.  Remove
some of the stuff in the <head>, and it works.

I don't know how many ads they have in the rotation, but it crashes pretty
reliabily.

I'm in the process of checking out the tree from scratch & rebuilding, but that
probably won't finish until tomorrow.

I did a "cvs checkout", created my mozconfig, did a "make -f client.mk

Surely this testcase can be reduced more.  Does it need that Flash in it?  Maybe
it does, since I don't have Flash and I have yet to be able to make it crash.

It may still be a bug in Gecko - reflow issues can be very timing- and

OK, so what seems to be happening here is the following (many thanks to shaver
for his patience and time in debugging this!):

1)  When constructing the <object>'s frame we enqueue the constructor execution
2)  When constructing the <input>'s frame, we end up calling ContentAppended on
    some anonymous content (called from nsTextControlFrame::InitEditor via some
    editor transaction stuff).  This causes us to process the attached queue
    before returning, which executes the constructor for the <object>.
3)  To execute the constructor we call WrapNative on the <object> to get a
    JSObject we can use as "this".  That ends up calling
    nsHTMLExternalObjSH::GetPluginInstance which calls
    FlushPendingNotifications.
4)  The flush causes a reflow, which tries to reflow a bogus frame tree (table
    cell frame has no inner block and inits an nsHTMLReflowState with a null
    frame) and hence crashes.  I'm not sure whence the bogosity arises exactly,
    but we're probably ending up notifying twice for the same content, reflowing
    while in the middle of frame construction, and all that jazz.

What I think should be done to fix this:

1)  Add asserts to nsCSSFrameConstructor to ensure that we are not reentering
    frame construction as we are here.
2)  Change nsTextControlFrame to init its editor off an event so we don't
    reenter in this case.
3)  Change nsDocument::FlushPendingNotifications to check whether it's safe to
    flush presshells before flushing (see code in
    nsHTMLDocument::FlushPendingNotifications to see how it works).  Change
    PresShell::IsSafeToFlush to say "no" while we're calling into the frame
    constructor.  This way we can't flush during frame construction.

Chances are, either #2 or #3 on its own will fix this bug, but I think it's
better to do both -- #2 will keep us from triggering the asserts from #1 and
running constructors at the wrong time, and #3 is good insurance in general.

I'm working on Item The First, but wanted to share roc's thought from IRC here,
for posterity and such:

< rocWork> I don't know enough about XBL to know whether the binding
attachment can be moved after the frame insertion. That would resolve the
problem completely.


    
    

    
  
Doing that should be safe (as in, "try on trunk" safe, not "do on branch" safe),
in my opinion.  I agree that that's also worth doing.

Most of the ReallyInitEditor changes are just indentation changes resulting
from the voidification of it (no way to prop failure to real caller anyway,
so...).  I can post a -w diff if that's easier to edit.

item 2: asynchronous initialize editor to avoid re-entering frame construction

sr=dbaron assuming the big reindented chunk doesn't change anything that would
surprise me (i.e, anything other than removing return values from returns). 
Use diff -b to check :-)

Also, should ReallyInitEditor be private, perhaps?  (It would require making
the callback functions friends.)

... although as bz points out, you should probably at least fix the comment at
the beginning of ReallyInitEditor and perhaps add an "XXX" comment that we
should simplify the existing code.

With comment changes; this is what I committed to Aviary branch.  I'll pull a
1.7 tree later and see if it fits in there; bz said it doesn't go so well on

Mike, if you can rip out the vestigial stuff on trunk, that would be great.

I believe your item 2 did apply to trunk, though; it was item 1 that did not
(and it was only slightly rotted).

    
    

    
  
Oh, I just said private rather than protected since I'm a little skeptical about
whether this can be subclassed.

could bug 263060 be a regression of this patch ?

Absolutely.  Calling select() should force editor init.

At the aviary meeting today, we decided we need to back this change out for the

This was backed out from the aviary branch due to the regression that was
introduced by this checkin.

This is still fixed on the trunk, AFAIK, so I think we want to leave this as FIXED.

This crash has spiked in Firefox 1.0.3 and 1.0.4 Talkback data and migth be
worth revisiting if we have time.  It's currently the #19 topcrash for 1.0.4,
and does not exist in current Trunk or Deer Park Alpha 1 Talkback data:
http://talkback-public.mozilla.org/talkback/fastfind.jsp?search=1&searchby=stacksig&match=contains&searchfor=nsHTMLReflowState%3A%3AInit&vendor=All&product=All&platform=All&buildid=&sdate=&stime=&edate=&etime=&sortby=bbid

Are we sure this wasn't checked into the Trunk?  Or if some other checkin fixed
this crash?

Adding topcrash info for future reference, but that doesn't mean we can't
consider a fix for a future Aviary branch release (since this is somewhat of a
regression).

I believe bug 350966 is a dupe of this one - the reduced testcase for this bug causes the same crash I'm seeing in my own (more) reduced testcase in 350966.

I'm seeing this in a fresh moz 1.7.14 with only flashblock 1.3.4 installed.

Is this still a problem now that bug 267833 is fixed?
Depends on: 267833

    
    

    
  
I don't get a crash from either of the testcases.
