Suspected problem in pthread_join()

[Tom Armistead]

Hi,

    I've been running the (ss20010424) RTEMS tests on a MCPN750
(PowerPC) and have found what may be bad behaviour of pthread_join()
when running psx08.exe.   The output from this test follows.  The
failure was that a pthread_join() to Task1 was expected to succeed but
instead failed with error ESRCH.  

    Some experimenting showed that Task1 had had run and exited by the
time the pthread_join() was invoked.  In this case pthread_join()
failed.  If I add additional computations to Task1 so that it is still
running when pthread_join() is invoked, the test succeeds.  So, it looks
like pthread_join() does not work if the thread of interest has already
exited.

     Can anyone confirm this?  

Thanks
