weave.blitz segfaults on nice-looking code (Trac #952)

Original ticket http://projects.scipy.org/scipy/ticket/952 on 2009-05-26 by trac user alextp, assigned to unknown.

>>> from scipy import weave
>>> from numpy import array,zeros
>>> n = 100
>>> dif = array([zeros(n)])
>>> difT = dif.T
>>> cov = zeros((n,n))
>>> weave.blitz("cov += difT*dif")
>>> n = 8319
>>> dif = array([zeros(n)])
>>> difT = dif.T
>>> cov = zeros((n,n))
>>> weave.blitz("cov += difT*dif")

Process Python segmentation fault

This is running under emacs, on a 32-bit processor. Running that line without blitz is perfectly OK. Is the problem on my end or is it some weird scipy bug?

It is also reproducible if the first call is to n=8319 (which just happens to be the dimension of some matrices in my work).

Oh, and

{{

scipy.version.version
'0.7.0'
}}

Python is 2.6, gcc is 4.3.3

Closing since weave is no longer a part of SciPy. This issue is now tracked at scipy/weave#7.
