Does this Erlang system have the glibc-2.4 fix applied? (See below.)

Does the problem go away if you build without thread support? There was
a bug in the sigaltstack() setup, but I've only seen the ill effects on
the SMP system, never on R10B. The fact that a 2.6.16-based kernel breaks
while a pre-2.6.16 kernel works hints strongly at the sigaltstack() bug.
