*red face* forgot about --debug.......

In case this helps, there are only 2 test lines in a single test in
r6535 which crash the interpreter on python-2.6.1-win32:
numpy/ma/tests/test_mrecords.py, in test_get(),
  - assert_equal(mbase_first.tolist(), (1,1.1,'one'))
  - assert_equal(mbase_last.tolist(), (None,None,None))

mbase[int].tolist() crashes Python in _Py_Dealloc(PyObject *op).
mbase.tolist() does not.

I'm not sure if there's a better way, but I've found it easiest to run
python via a debug run from within VS, installing and testing numpy
from there.  The 2.6.1 sources build fine with VS2008.
