Hello!
Firefox-20 would not build with the regular compiler, so I installed the
shiny new gcc-4.8
This builds (though the attached patch is required -- at least, on
i386), but dies on startup from "illegal instruction".
If I start under gdb, instead of SIGILL, I see segmentation fault --
inside XRE_AddStaticComponent in libxul.so
Using -safe-mode does not help. I tried switching to 17-esr, but seeing
the same problem. The OS 8.2-STABLE/i386, running on a dual Opteron system.
Any clues? Thanks!
