John Baldwin dc3566067a Ensure thread library is initialized in pthread_testcancel(). ... Call _thr_check_init() before reading curthread in pthread_testcancel(). If a constructor in a library creates a semaphore via sem_init() and then waits for it via sem_wait(), the program can core dump in _pthread_testcancel() called from sem_wait(). This is because the semaphore implementation lives in libc, so the library's constructors can be run before libthr's constructors.
