Debugging and jumping to line 3 makes Python crash.
For instance:

python -m pdb
(Pdb) j 3

For reference, here is the crash:

rdmurray@hey:~/python/p33>./python -m pdb
> /home/rdmurray/python/p33/<module>()
-> with open('test') as f:
(Pdb) j 3
python: Objects/frameobject.c:207: frame_setlineno: Assertion `blockstack_top > 0' failed.
zsh: abort      ./python -m pdb

frame_setlineno() doesn't keep track of with blocks. Here's a patch.
