For some reason, the PC where the SIGILL occurs seems to change every
time I re-run Vuze.

Attached is a gdb stack trace that seems to point to some JITed
javascript code as the culprit (gdb says "No function contains program
counter for selected frame" for the innermost stack frame; and the
second to innermost is in libjavascriptcoregtk-1.0-0).

In this run, the eip at SIGILL is 0xabda3f42:

(gdb) x/10i 0xabda3f42
=> 0xabda3f42:  movsd  %xmm0,(%eax)
   0xabda3f46:  mov    $0xad967190,%eax
   0xabda3f4b:  movsd  %xmm1,(%eax)
   0xabda3f4f:  mov    $0xad967198,%eax
   0xabda3f54:  movsd  %xmm2,(%eax)
   0xabda3f58:  mov    $0xad9671a0,%eax
   0xabda3f5d:  movsd  %xmm3,(%eax)
   0xabda3f61:  mov    $0xad9671a8,%eax
   0xabda3f66:  movsd  %xmm4,(%eax)
   0xabda3f6a:  mov    $0xad9671b0,%eax

I'm unfortunately no SSE expert and I don't know what, if anything, this
instruction is supposed to do on my CPU (AMD Athlon(tm) XP 3200+ ; it
does have sse in the flags, see my /proc/cpuinfo in the Java crash
report attached above).
