The reason for the lockup is that the cleanup handlers pthread_cond_wait and the cleanup handler your code register are not executed in the correct order. And this happens because you are using the LinuxThreads headers. If you'd use the NPTL headers everything would work fine. Since we unfortunately cannot pull the plug on the LT headers yet Jakub came up with a patch which should handle this case. The current CVS has it, as will future releases and updates. - -- - --------------. ,-. 444 Castro Street Ulrich Drepper \ ,-----------------' \ Mountain View, CA 94041 USA Red Hat `--' drepper at redhat.com `--------------------------- -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) iD8DBQE/qc732ijCOnn/RHQRAicvAKC6X8Dyk0p17/7xSR0EFgcgSrZZ+wCgzW2W y8K0mr4MGcjOcJu0rIW+YMw= =Bwg0 -----END PGP SIGNATURE-----
