I'm not sure we should do anything about this.
We have a warning if the compiler can detect non-positive value at compile
time,
but we certainly can't ever issue any diagnostic at runtime for num_threads
0 (because the implementation uses that value to mean no num_threads clause was
present) and I'm not convinced the runtime library needs to be verbose to
stderr. So e.g. silently assuming just one thread is IMHO better than doing
gomp_fatal in there. You shouldn't expect any particular behavior from program
which triggers undefined behavior.
