There are a number of ways to set up for debugging. The one that works 
for me is to do


git clean -xfdd

CFLAGS='-O0 -g3' python runtests.py -b

gdb --args python runtests.py -t file/I/with/the/test/I/want.py


The "git clean" should make sure you are not using pre-compiled 
c-extensions.

There are variants of this if you are using an IDE or like to use 
setup.py directly
