[Matrix-SIG] Re: Floating point exception when sort is given zero length list

[Paul F. Dubois]

I'm sorry for the confusion. When I said this was fixed I forgot to check
WHEN it was fixed. It was fixed after the last release so naturally you do
not have it. Here is our Perforce entry:

Change 608 by motteler@motteler on 1998/11/17 15:04:01

 (ZCM 11/17/98) Fixed multiarray so that it wouldn't core dump python
 when attempting to argmax/argmin, sort, or argsort an empty sequence.
 Instead it now throws an exception and gives an informative comment.
