2003-04-01 Ulrich Drepper <drepper@redhat.com> * pthread_create.c (deallocate_tsd): Clear/free memory after the last round, not the first. Use specific_used flag instead of local found_nonzero variable. Use THREAD_[SG]ETMEM where possible. (__free_tcb): Don't call deallocate_tsd here. (start_thread): Call deallocate_tsd here. * pthread_setspecific.c: Set specific_used flag really only when needed. * Makefile (tests): Add tst-tsd3.c * tst-tsd3.c: New file.
