[MATRIX-SIG] Bug report - seg-fault

I recently found the following anti-social behaviour when multiplying
arrays of zero length on one dimension. Python seg-faults when the second
dimension is mismatched by 4 or 5 (it depends...).  Can anyone else
reproduce this? I haven't tried to track it down in the C code, but maybe
I'll get a chance to try to next week...

>>> from Numeric import *
>>> ones((0,1))*ones((0,2))
zeros((0, 2), 'l')
>>> ones((0,1))*ones((0,3))
zeros((0, 3), 'l')
>>> ones((0,1))*ones((0,4))
Segmentation fault (core dumped)
