I was testing Jumbo but this is a core problem. The problem is this pragma: #pragma omp parallel for default(none) private(index) shared(warned, count, crypt_out, saved_key, saved_salt, stderr) Compiler dies unless I change it do either #pragma omp parallel for default(none) private(index) shared(warned, count, crypt_out, saved_key, saved_salt, __iob) ...or just (That block is '#if __sun' and I'm not 100% sure __iob will work on just *any* __sun?) #pragma omp parallel for However, after fixing that I still have some problems. First, it does not actually seem to use OMP although it prints it does: Warning: OpenMP is disabled; a non-OpenMP build may be faster Benchmarking: crypt, generic crypt(3) DES [?/32]... DONE Many salts: 864 c/s real, 872 c/s virtual Only one salt: 872 c/s real, 872 c/s virtual Will run 8 OpenMP threads Benchmarking: crypt, generic crypt(3) DES [?/32]... (8xOMP) DONE Many salts: 855 c/s real, 838 c/s virtual Only one salt: 864 c/s real, 842 c/s virtual Second, only seen in --test=0 (all formats) runs so far, it sometimes just hangs after printing this: Testing: crypt, generic crypt(3) DES [?/32]... (8xOMP) It hangs forever with 0% CPU load. I don't actually care about this (we're just doing Jumbo BE tests :) but now you have been notified. BTW the man page on that machine does state that crypt() is MT safe. magnum
