Thanks, it looks good now:

Program received signal SIGILL, Illegal instruction.
[Switching to Thread 0xab7feb70 (LWP 12776)]
0xaec24272 in ?? ()
(gdb) disassemble 0xaec24272,+10
Dump of assembler code from 0xaec24272 to 0xaec2427c:
=> 0xaec24272:  xorpd  %xmm0,%xmm0
   0xaec24276:  cvtsi2sd %edx,%xmm0
   0xaec2427a:  jmp    0xaec2428a
End of assembler dump.

xorpd is a SSE instruction :(. I wonder if this is just a compiler flag problem or this crap is generated by Firefox JIT compiler?
