218990 - Selecting Boomarks -> File Bookmark... leads to 100% cpu usage and non-responsive browser.

Status: RESOLVED INVALID

(SeaMonkey :: Bookmarks & History, defect)

Description

[James Blanford]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030910
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5b) Gecko/20030910

This looks a lot like bug 91782.  I still have a mozilla built on 20030903 that
doesn't have this problem.  I first noticed it on 20030909 with a gtk2 build and
tried again on 20030910 with the old reliable gtk-1.2.

It also happens with Bookmarks -> Manage Bookmarks... with a slight difference.
 With File Bookmarks I see only the window title of the bookmark manager.  With
Manage Bookmarks I see the title and frame, but not the contents.  This could be
a bad interaction with my window manager.

Comparable key sequences work the same as the menu selections.

Reproducible: Always

Steps to Reproduce:
1.  Go to any page, local or remote
2.  Select Bookmarks -> File Bookmark...


Actual Results:  
The title bar of the bookmark manager appears, but not the content of the
bookmark manager, cpu usage goes to 100% and mozilla stops reponding.

Expected Results:  
The bookmark manager should appear and allow me to select a folder to file the
bookmark in.

The two builds I have noticed this on were just before and after the 1.5 release
branch.  My build is very minimal - a browser with xft and crypto.

I tested with a new default profile and no extensions or themes.

please try a clean profile.
can you grab a stacktrace from gdb?  (preferably with symbols)

Comment 2

[James Blanford]

Sorry, it's a compiler issue.  The problem appears only when I use
gcc-3.3.2-0pre3, released about Sep 8, 2003 by Debian.  With earlier versions of
3.3 or 3.2 this problem does not occur.  With the aforementioned gcc-3.3, I
can't even build a mozilla with debugging symbols.  The compile hangs at
libgklayout.so.

If you have anything you want me to try, well - mention it and I'll try.  I
suppose it could be a bug in mozilla exposed by the gcc project's continuing
efforts to enforce standards, but I think it's a compiler bug.

reopening.  FIXED is reserved for bugs fixed by Mozilla patches.

Comment 4

[Andrew Schultz]

marking INVALID -- this is not a Mozilla bug.

gcc hanging trying to link libgklayout.so is definitely a gcc bug.

OK, the problem compiling a debug version was my fault.  Once I did get a debug
version, the problem went away.  So I recompiled readding this line to .mozconfig:

ac_add_options --disable-debug

and changing nothing else.  I rebuilt mozilla and the problem recurred.  Here's
what I got from gdb:

I still only get the problem with the most recent Debian gcc-3.3.

We can put this one to rest.  It appears to be Debian BTS #210848 in the g++
compiler.  At any rate, the problem has disappeared when the exact same source
is compiled with g++-3.3.2-0pre4.

I have the same problem:

I select Bookmarks -> Manage Bookmarks..
and it hangs and goes to 100% CPU usage.

gcc version 3.3.2 20030924

No matter whether I use --disable-debug or not, only --enable-optimize makes a
difference for me. If I do not build with -enable-optimize it works, if I do
build with -enable-optimize it does not work.
