Is this an SMP or uniprocessor virtual machine?

I see frequent "signal 11" failures from gcc when putting an SMP
virtual machine under load.  The same load on a uniprocessor
virtual machine works fine.  This is 6.2-STABLE;  I haven't tried
-CURRENT.  VMware Server 1.0.3, AMD-X2, ECC memory, Windows XP
64-bit host.
