Memory usage spikes while trying to parse_dammit certain code.

[Zerrien]

With the following code:

def c (d):
    pass
def a(b):
    c#( # Adding/removing this "(" causes memory usage to spike.
    return None

From my testing (which is a bit shaky due to the nature of the bug):

• The c function needs to be defined, and needs to have a parameter.
• The a function needs to return something.
