You can get a debug version of your extensions without using a debug
version of python - using a debug version of python for your
extensions is a lot of work (especially on windows), and you will have
to dig in the code yourself to do it, most likely.

To build a debug extension of an extension with the normal python
interpreter, use the -g option, e.g.:

python setup.py build_ext -g
