"illegal instruction" is a compiler bug, right?

I just got a report from a user of the Octave RPM on FC4 that he got a 
crash due to an illegal instruction on an old AMD K6-3. I was able to 
duplicate this on a Pentium 233 (yes, I still have one), but not on my 
Centrino laptop. This shouldn't happen, right? The configure command 
from the spec file is:

CXXFLAGS="$RPM_OPT_FLAGS -D_GNU_SOURCE" ./configure \
        --enable-shared=yes --enable-lite-kernel --enable-static=no \
        --prefix=%{_prefix} --infodir=%{_infodir} --libdir=%{_libdir}

This should produce something that runs on an i386, right? I just wanted 
to verify before I create g++ bug in bugzilla.
