The problem is that you get into library-interaction bugs like the one discussed here: http://archives.postgresql.org/pgsql-general/2007-11/msg00580.php http://archives.postgresql.org/pgsql-general/2007-11/msg00610.php I suspect what you're seeing is the exact same problem on a different glibc internal mutex: the mutex is left uninitialized on the first trip through the code because the process is not multithreaded, and then after OpenBabel gets loaded the process becomes multithreaded, and then it starts trying to use the mutex :-(. Since the glibc boys considered the other problem to be their bug, they'd probably be interested in fixing this one too. Unfortunately, you picked a Fedora version that reached EOL last week. Update to FC7 or FC8, and if you still see the problem, file a bugzilla entry against glibc. But having said all that, that still only addresses the question of why the process hangs up during exit(). Why the double-free report is being made at all is less clear, but I kinda think that unexpected multithread behavior may be at bottom there too. regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
