On a PS5 (firmware 12.70), of the values 0, 1, 2 and -1, pthread_condattr_setpshared accepts only 0 and leaves the attribute unchanged otherwise. pthread_condattr_getpshared reports 0 and returns EINVAL for a null, uninitialized or destroyed attribute, also with a null output. With an initialized attribute a null output crashes the console; here it throws. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
