228280 - crash when clicking on a radio button

Status: RESOLVED WORKSFORME

(Core Graveyard :: GFX: Gtk, defect)

Description

[Hannes Wallnoefer]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6b) Gecko/20031210
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6b) Gecko/20031210

My Mozilla 1.6b/CVS trunk build crashes whenever I click on a radio button in
any web page. This doesn't happen with the 1.6b build from ftp.mozilla.org, so
it definitely has to do with my build options/environment (GTK2, XFT,
optimization for i686).  My box is an up-to-date SuSE 9.0, the gcc version is
gcc (GCC) 3.3.1 (SuSE Linux), I add the contents of the .mozconfig file below.

Reproducible: Always

Steps to Reproduce:
1. Go to any web page containing a radio button form element
2. Click on a radio button

Actual Results:  
The radio button becomes gray and Mozilla crashes after some fractions of a second


# sh
# Build configuration script
#
# See http://www.mozilla.org/build/unix.html for build instructions.

# Options for 'configure' (same as command-line options).

[Olivier Cahagne]

can you post a minimal testcase and attach a stack trace via "create a new
attachment" by compiling without --disable-debug ?

Comment 2

[Hannes Wallnoefer]

I recompiled with debug enabled, and the bug has gone. With debug disabled it
really happens with every every HTML radio button. 

Comment 3

[Olivier Cahagne]

do you crash with less aggressive compilation flags, I mean removing the lines:

ac_add_options --enable-reorder
ac_add_options --enable-cpp-rtti
ac_add_options --enable-optimize='-O3 -march=i686 -mcpu=i686'
ac_add_options --enable-cpp-exceptions

You have 2 --enable-optimize lines btw

Comment 4

[Boris Zbarsky [:bzbarsky]]

You can get a useful stack from an optimized build by adding "-g" to the
optimization flags.

Over to blizzard, since this sounds like an xft or gtk2 issue.

Comment 5

[Hannes Wallnoefer]

Attachment: stack trace

Here's a stack trace obtained from gdb. I hope it's useful, I'm not that good
at debugging C programs. If it isn't, let me know what to do.

[Hannes Wallnoefer]

Olivier: I don't crash without the config lines you list. I'll throw some of
them back in to find out which one causes the problem.

Comment 7

[Hannes Wallnoefer]

OK, I found out: the problem comes from the -march=i686 flag. If I change that
to -march=i586, the bug has gone. So I guess it isn't a bug after all (but I'm
not versed enough in gcc and gtk to tell). Interesting that the problem appears
with radio buttons and only radio buttons, though.

Marking worksforme since you're messing with untested compiler options.
