As pointed out by Hodgestar on #scipy

The bug is present in numpy 1.3, but is reproducible using trunk on the sparc buildbot.

This occurs since the multiarray module (and, hence, also umath) needs some initialization before it works correctly, and apparently some cleanup code assumes the initialization really has been performed before the interpreter is exited. The initialization is done on the Python side when numpy.core is imported.

I don't think this is a bug that can occur during normal operation (you don't get it from import numpy.core.umath), so closing as a wontfix.

While it shouldn't occur in normal operation, and wontfix is probably the right choice, it is worth noting that this is triggered by pylint 0.20.0 - see http://www.logilab.org/ticket/23009 .

Ummh, reopening then, in case it's possible to track down if there's a way to track down where exactly the bug comes from.

Turns out to be the same issue as #2061
