Ryan Stone aad93b043a r179417 introduced a bug into pthread_once(). Previously pthread_once() ... used a global pthread_mutex_t for synchronization. r179417 replaced that with an implementation that directly used atomic instructions and thr_* syscalls to synchronize callers to pthread_once. However, calling pthread_mutex_lock on the global mutex implicitly ensured that _thr_check_init() had been called but with r179417 this was no longer guaranteed. This meant that if you were unlucky enough to have your first call into libthr be a call to pthread_once(), you would segfault when trying to access the pointer returned by _get_curthread(). The fix is to explicitly call _thr_check_init() from pthread_once(). Reviewed by: davidxu Approved by: emaste (mentor) MFC after: 1 week		2011-04-20 14:19:34 +00:00
