User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9a9pre) Gecko/2007101011 Firefox/3.0a9pre
Build Identifier: 

It could be related in some way to bug 390898, pixman-compose.c file is indeed in crash, but at another line.

Here is what I get when I ran a debug enabled build, and tried to print gmail start page :

#0  0x00002b773a1cbb03 in fbFetchPixel_a8r8g8b8 (image=0x1a95020, 
    bits=0x401a94d80, offset=0, indexed=0x0) at pixman-compose.c:705
Cannot access memory at address 0x7fff71b0c138

Reproducible: Always

Steps to Reproduce:
1.Build yourself minefield
2.go to gmail
3. file / print / ok
Actual Results:  
Crash - see error line that gdb gave me.

Expected Results:  
printing ? ;)

I am using ubuntu gutsy gibbon up-to-date. I also use gcc-4.2 to build minefield.

Anyway, here is the .mozconfig I used to build my debug build :

"#
# See http://www.mozilla.org/build/ for build instructions.
#

export CC=gcc-4.2
export CXX=g++-4.2

. $topsrcdir/browser/config/mozconfig

# Options for 'configure' (same as command-line options).
ac_add_options --enable-optimize="-O2 -g"

ac_add_options --enable-default-toolkit=cairo-gtk2"

I will try to see if I can reproduce the bug with a young official nightly build asap.

I tried with the latest hourly, and no crash. Is this a bug in gcc 4.2 ? I will try with gcc 4.1 and see if it still crash.

Erh, crash also with gcc 4.1.

Stinks like a gutsy gibbon bug. I will try in an OpenSuSE 10.3 x86_64 in a vmware virtual machine and see if it still crash. It will take about 3 or 4 hours before I can see if my idea is right or not.

Was this fixed by bug 390898?

Please reopen the bug report if it still occurs in a recent trunk build.

-> WORKSFORME
