I've had similar problems on gsyprf11, but recent kernels seem to be
better.  I believe that this is more likely on SMP kernels and we have
never had a stable one on gsyprf11.  You can kill expect and GCC will
move on to the next suite.  I haven't seen this on the C3750.

This definitely isn't a GCC problem.  The problem never occurs under
hpux.  It's probably some kind of timing or locking issue that just
happens to get tweaked by a particular test.
