[MATRIX-SIG] Bug report - seg-fault

[Jean-Bernard ADDOR]

Hy !

It seems to give the expected result on sunos.

Python 1.4 (Apr 12 1997)  [GCC 2.7.2]
Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
>>> 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))
zeros((0, 4), 'l')
>>> 


A bientot,

	Jean-Bernard
