This sounds awfully reminiscent of the bug I recently mentioned: http://aspn.activestate.com/ASPN/Mail/Message/numpy-discussion/3312099 We left a fresh run over the weekend, but my office mate is currently out of the office and his terminal is locked, so I don't know what the result is. I'll report shortly: we followed Travis' instructions and ran with a fresh SVN build which includes the extra warnings he added to the dealloc routines. You may want to try the same advice, perhaps with information from both of us the gurus may zero in on the problem, if indeed it is the same. Note that I'm not positive it's the same problem, and our backtraces aren't quite the same. But the rest of the scenario is similar: low-level memory crash from glibc, very long run is needed to fire the bug, potentially millions of calls to both numpy and to f2py-wrapped in-house libraries.
