Which platform are you on ? And which version of scipy are you using ?
There were known defects on mac os X which have been solved recently.

The matrix cannot be generated ? Maybe you could try to reproduce the
crash with a smaller matrix. A backtrace would be useful, too. Under
linux or mac os X, it is relatively simple to do so:

gdb python
run myscript.py
... -> crash
