pthread_cond_signal hangs with glibc 2.3.2

[Truxton Fulton]

Hello,

I recently installed redhat 9 and found that my program
that runs well on other platforms got deadlocked.
I tracked it down to a call to pthread_cond_signal which
never returns.  The condition variable was properly
created.  I installed the rpm update for glibc which
makes a reference to bugfixes for pthread_cond...
but the problem persisted.  I couldnt find anything
similar in the gnats bug database.
Is this a known problem?

Thanks,
