I don't think I can.

I cannot reproduce that problem.

I just guessing but I think the /lib/tls/libpthread.so.0 is the new
NPTL pthreads library. valgrind supplies it's own threading stuff,
perhaps it doesn't yet support NPTL. Can you force the build to use
the LinuxThreads library (set LD_ASSUME_KERNEL perhaps)? You may have
to recompile, I don't use a NNPTL system so I can't really help.
