SMT should be i386 only at this stage so it rules that out.

x86 is pretty stable, that I am sure of. I have run it on quite
a lot of boxes, SMP P4, NUMAQ, SMP P3s, UP, etc plus countless
people testing -mm.

It wouldn't surprise me if there is a problem with another
architecture... but then again as you say Anton is running it
OK so I dunno. Maybe it is a compiler bug?
