Linuxthreads is pretty much broken when you call pthread_create after pthread_join and stack memory is reused for whatever reason. The problem is the corrupted doubly linked list of active threads. The linked list is maitained by pthread_handle_create and pthread_exited. However, memset in pthread_allocate_stack can trash the doubly linked list before the dead threads are removed from the active thread list. I don't know what is the best fix. It can be very tricky. I am enclosing the testcase here. H.J.
