It sounds like the same problem that was reported in this thread:

http://thread.gmane.org/gmane.comp.python.numeric.general/17456/focus=17465

A friend of mine says the windows binary of 1.0.4 also hangs on eigh
and lstsq (so linalg in general). I don't have that problem on 1.0.5
compiled on GNU/Linux.
