I think it points to a pthread > issue. Further to this point, I used strace to look at pthread6 while it was executing. I see a continuous stream of sched_yield calls with a few nanosleep calls every so often. Thus, I think the code is spinning in __pthread_acquire. This would happen if spinlock/mutex initialization is broken. Proper initialization is needed on hppa-linux because locked is 0 and unlocked is 1.
