I get the same result with Pythin 3.3.0a0 on MacOS X 10.6:

93> ./python.exe -m pdb /tmp/script.py
> /tmp/script.py(1)<module>()
-> print(1)
(Pdb) j 7
Assertion failed: (blockstack_top > 0), function frame_setlineno, file
Objects/frameobject.c, line 208.
Abort trap

The assertion that fails is in this code fragment:

        case POP_BLOCK:
            assert(blockstack_top > 0);


This looks like a genuine bug in the CPythin interpreter to me.
