--- Comment #4 from Tom Hughes <tom@compton.nu> ---
Well it doesn't look like there was a SIGILL from the kernel so I think it must
be the instruction decoder in the JIT which is triggering it, which is unusual
as the JIT normally generates it's own error if it can't handle the
instruction.

The problem instruction appears to be at 0x405ED3C in __intel_sse4_strrchr in
libirc.so - any chance you could disassemble that function and show us a few
instructions around that point, given VEX hasn't reported the problem
instruction in the normal way...
