Sorry about that. I spoke too soon. There seems to be some kind of runtime decay and a dependency on semaphore.h. Running the same test or the two tests alternating works for about three times just as expected but further runs fail as before. A reboot fixes that and gives me another few chances. This only applies to read(). sem_wait() always works. If the test code includes semaphore.h but doesn’t even use any of its functions it fails right away, just like before. A reboot doesn’t help. It’s getting weirder by the day...
