I have seen the same behavior on a Dec Alpha running RedHat Linux, with Numeric compiled with gcc. The other random pieces of Numeric that I tried seemed to work correctly.

Hi, I posted this message on the python-list a while ago and did not hear anything .. so I try here :)
I built Numeric on a Dec Alpha under OSF1 V4.0. I built fine but when I ran it I witnessed strange behavior.
a = Numeric.identity(4) a.shape = (16,)
would raise an exception about the size of the array needing to remain the same ???
Using the debugger I found in arrayobject.c:2201
if (PyArray_As1D(&shape, (char **)&dimensions, &n, PyArray_LONG) == -1) return NULL;
After this call shape [0] is 4 BUT shape[1] is 0 !
I changed the code to if (PyArray_As1D(&shape, (char **)&dimensions, &n, PyArray_INT) == -1) return NULL;
and got the right result.
Did anyone else run into this kind of preblems ? what is the correct way to fix that ?
thanks
-Michel
