[Boost-users] read_write_mutex assertion on multiprocessor Wintel

As I reported earlier, read_write_mutex asserts in debug mode (VC71), apparently seeing false wake-ups on a condition variable. I was able to do this with just a simple group of threads locking a RWM in tight loops, with one writer and a few readers. The new information is that I am runing this on a dual-Xeon with hyper-threading enabled (so four apparent CPU's), and I'm thinking that maybe boost libs don't get exercised on this kind of hardware very much. Is is possible that a condition::notify_all() happens on each processor? Has anyone else seen this? For now, I just removed the asserts and rebuilt. Synchronization seems to be unaffected in my real-world stress test of RWM. jh
