I cannot reproduce the problem with QEMU emulating a pentium 3 CPU.

We have had problems with old i386 CPUs in the past, see #930935 in
particular, but there's no SIGILL here.

Also, this is an SSE instruction, but your processor supports it:

Do you think you can provide a backtrace with the -dbgsym package
installed?

Thanks,
