strace output of mozilla during crash
32.76 KB, text/plain
Details
strace output for "mozilla --sync"
26.67 KB, application/x-tar
Details 
User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030319 Debian/1.3-3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030319 Debian/1.3-3

I get the same problem on the the builg logs listed at
http://buildd.debian.org/build.php?pkg=xprint-xprintorg (at least the recent
ones dated March 29).

I'm tying to find what's gone wrong with building xpawhelloworld.  I open up the
Find dialog with Ctrl-F, type in xpawhello.  The first few entries, relating to
setting up the Makefile etc, are OK.  But when I'm about to get to the actual
build entry (gcc -o xpawhelloworld ...), Mozilla (1.3) just crashes, just like
that.  It also crashes if I start the search from the bottom of the page,
searching backwards.

I could previously read the older buildlogs OK, but I've since upgraded to
Mozilla 1.3, so I wonder if it's new 1.3 code causing the problems.

I'm running on an older laptop (Pentium II, 233MHz) with only 96MB RAM, I don't
know if that's relevant.

Reproducible: Always

Steps to Reproduce:
1. load 
http://buildd.debian.org/build.php?&pkg=xprint-xprintorg&ver=0.0.8.cvs20030328-1&arch=alpha&file=log
2. Open Find dialog with Ctrl-F
3. Search for xpawhello
4. Keep searching till you would otherwise reach the "gcc =o xpawhelloworld"
line, at which point Mozilla completely crashes.
Actual Results:  
Mozilla blinks out of existence, it crashes.

Expected Results:  
Should display the line starting with "gcc -o xpawhelloworld".
I can't reproduce this crash using 20030302809/win98.

This might be related to Bug 174972 (although that seems to happen on the find
dialog creation)

Reporter, is it possible for you to try this on a mozilla.org nightly from the
past few days (ftp.mozilla.org/pub/nightly/)? If you can still reproduce it,
this should be in the 'Search' component and have the 'crash' and 'stackwanted'
keywords.
worksforme with linux trunk 20030328 and 1.3 release.  you might try a clean
profile.

if you don't try out a .mozilla.org build, you'll need to provide a stacktrace
with gdb (preferably from a build with symbols)

Oops. Sorry, I suck. I made the mistake of trusting that other similar bugs has
been filed correctly. 

I'll try this on linux later on.
Yes, I meant
http://buildd.debian.org/fetch.php?&pkg=xprint-xprintorg&ver=0.0.8.cvs20030328-1&arch=alpha&stamp=1048959725&file=log&as=raw
for the the test page, sorry for the mess-up.

I'll let you know if I'm able to generate a stack trace or if cleaning my
profile works. Currently I'm working with the Debian build (1.3-3).

I've since noticed the crashes happen not only during a Ctrl-F search, but also
simply by scrolling down other pages, for instance
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=186959.  I presume it's the
same bug.

I've changed the title of this bug report accordingly.

It's worth mentioning that other users have reported mozilla1.3 crashes on the
Debian Bug Tracking System.  I presume again these are related to the bug I'm
experiencing.  Suggestions there are that the problem is related to fonts (using
the libxft2 engine).  I couldn't say if it's a C++ ABI problem due to Debian's
recent switch to gcc3.2.

I'll also attach the relevant part of an strace here.  Will that be sufficient,
or should I strictly give a gdb trace?
Summary: crashes while doing find search on large parge → crashes while moving along some pages (during find or scroll down)
This is the strace output from accessing
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=186959
and trying to scroll down.  I've just included the relevant portion leading up
to the crash, starting from where the page is accessed.

p.s. My apologies for the repeated paragraphs in the preceding comment, I don't
know where they came from!
worksforme with linux trunk/CVS/gtk2/xft

the strace only shows a truetype fonts being read and maybe an X Error.  stack
trace (with mozilla --sync) would be more useful.

this could easily be a dupe of 173204
Blocks: xft_triage
Here's the strace output for "mozilla --sync".	I've only included the last
part of the strace, relating to the crashing page, and gzipped it to save
space.

--sync also says:

The program '<unknown>' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 32341 error_code 1 request_code 252 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
I tried running mozilla from a new user (hence, with a freshclean  profile), but
it crashes in the same way.
stack trace == from gdb and would show what Mozilla is trying to do
system trace == from strace
The default Debian build (now 1.3-4) does not have debugging symbols included,
so I can't use gdb right now.  I'll report back when I can get a debugging or
recent CVS version.
I've now tried the nightly build (2003041322).  It does not crash on either of
the two urls I've given.  On the other hand, the nightly build is made against
GTK+1.2, not GTK+2.  If the problem is in libxft2 font handling, then it won't
occur until the nightly build is made against GTK+2.  So the positive test of
the nightly build is inconclusive.

Are there any other GTK+2/libxft2 builds of recent mozillas, apart from Debian's
(which has debugging symbols stripped), that I could test?
there are RPM builds with gtk2/xft here, but I don't know if you can use the
RPMs with Debian.
http://download.mozilla.com/pub/mozilla/nightly/experimental/gtk2/

the stack from the Debian won't be incredibly useful, but there are a few known
crashes (none of them Mozilla's fault) and the stack (even without symbols)
might show itself to be one of those crashes.

Other things to look at is if you have any MS .fon fonts or if any of your
truetype fonts are not readable.
ftp://ftp.mozilla.org/pub/mozilla/nightly/experimental/gtk2 has some gtk2
builds, but I don't think that they're debug builds. They also appear to be
rpms. There are also xft builds in
ftp://ftp.mozilla.org/pub/mozilla/nightly/experimental/xft with the same
restrictions. Therefore, my best suggestion is to grab the source and build
Mozilla with the correct options set. 
the RPM builds don't have symbols stripped, so a useful (if not detailed) stack
can be obtained.
The 20030418 GTK+2 rpm from
http://ftp.mozilla.org/pub/mozilla/nightly/experimental/gtk2 does not crash.

I guess that implies the bug has been fixed.

I'd like to leave the bug open until I can confirm the upcoming Debian builds
also work.  If they don't, we'll know it's some Debian library problem, not a
mozilla problem.

The Debian build of mozilla 1.4 is no longer crashing, so I think this bug can
be closed now.
