Bug 326579 – After upgrading to gcc 4.4.3 the system got various segfault

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Dell'Aica Valentino 2010-07-02 08:45:06 UTC]

After upgranding gcc stable to 4.4.3 I notice segfault in varius programs. I try in order:
revdep-rebuild; result: system clean
gcc-config 4.4.3; fix_libtool_files.sh 4.3.4; emerge -1 libtool; revdep-rebuild; result: syste clean;
emerge -ev system;
emerge -ev world; result: segmentation fault during installation of openoffice.

The program who has segfault are mozilla-firefox, mozilla-firefox-bin, mplayer.

Maybe this bug can be realated to optimization in gcc 4.4.3.

Portage 2.1.8.3 (default/linux/x86/10.0, gcc-4.3.4, glibc-2.11.2-r0, 2.6.32-gentoo-r7 i686)

Use sane flags, like -O2 instead of -O3. This is most likely a duplicate of bug 270120 (and will be marked as such if no futher information is given)
