hi there, I am adding this to this thread and not to the trac, because I
am not sure whether it adds noise or a piece of info. I just downloaded
the scipy trunk and built it, and ran nosetests on it, which bombed
instantly....
So I tried to get into subdirs to check test scripts separately..... and
here is one :
[co...@jarrett tests]$ ~/.local/bin/ipython test_integrate.py
---------------------------------------------------------------------------

the bomb is the same, but the context seems different... I leave that to
the experts :)

Hi,
I think I managed to find this. I reverted back my svn versions ($svn
update -r 8262) and cleaned both the build and installation
directories.
It occurred with changeset 8262 (earlier changesets appear okay but
later ones do not)
http://projects.scipy.org/numpy/changeset/8262
Specifically in the file:
numpy/core/code_generators/generate_ufunc_api.py
There is an extra call to that should have been deleted on line 54(?).
Py_DECREF(numpy);
Attached a patch to ticket 1425
http://projects.scipy.org/numpy/ticket/1425
Look like my bad. I'm out of town at the moment so someone else needs
to apply the patch. That whole bit of code could probably use a
daylight audit.
