Invoked as "acc_wait_async ([...], acc_async_sync)" (as used in a test case that I'll soon submit/commit), we'll end up with "aq2 == NULL", and will segfault in the nvptx "openacc.async.serialize_func".
What does "wait async(acc_async_sync)" supposed to mean? Instead of fixing it here, will it make more sense to have the serialize_func hook to accommodate the NULL asyncqueue? Chung-Lin
