Logged In: YES user_id=701470 I can confirm this problem. I am using scons to build my project on AIX. I could not run parallel builds (-j4) on AIX. Randomly, but very often xlC invocation would stuck and I have 4 xlCcode hanging and taking all CPUs. After adding HAVE_BROKEN_POSIX_SEMAPHORES for AIX and rebuilding Python parallel builds on AIX are fine. Trying first fix with changing 0 to 1 in sem_init also resolved this problem, but I started to get some other unexplained error from scons, so had to deactivate semaphores all together. Albert, thanks for this report, it helped a lot.
