When compiling Firefox 1.5.0.5 with gcc 4.1.1 and the CFLAGS "-march=pentium4 -Os -pipe -fomit-frame-pointer" going to any site that uses javascript firefox will crash with a segmentation fault. When compiling with -O2 (as my flags have been set below), the problem disappears.

Looks like I spoke too soon. For some reason it has started crashing again when I go to gmail, slashdot and facebook. Any ideas on what would cause this or how to fix it?
No, not really enough info here. Start with clean profile without any plugins.
