> Does this reduced test work with -std=gnu++11 -pthread ?
Unfortunately not, I still get
22 : Invalid argument
Only if I add an explicit call to pthread_mutex_init does the testcase
work.
I've no real idea why this happens. pthread_mutex_init(3) states
Use the PTHREAD_MUTEX_INITIALIZER macro to statically initialize a mutex
without calling this routine. Statically initialized mutexes need not be
destroyed using pthread_mutex_destroy(3). Use this macro as follows:
pthread_mutex_t mutex= PTHREAD_MUTEX_INITIALIZER
Only normal mutexes can be statically initialized.
While I do have Tru64 UNIX sources, libpthread is only partially
included and the implementation of pthread_mutex_lock is missing.
