OK, I can reproduce this now.  I didn't see it before because the
Debian gcc-3.3.2 package failed to install unwind.h and as a result,
NPTL was built with HAVE_FORCED_UNWIND turned off.  Now that it's on,
I'm also seeing lots of NPTL failures (starting with the ones you
mention).  Let me take a look.
