This is the string it's trying to delete:

"abcdfeghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789" FYI, that string appears only in shlex.py (split across two source lines). Maybe that will help whittle it down.

Here's some code from Lib/compiler/transformer.py:

def atom_string(self, nodelist):
    k = ''
    for node in nodelist:
        k += self.decode_literal(node[1])
    n = Const(k)
    n.lineno = nodelist[0][2]
    return n

what does this make you think of? Yes, it's the new += string optimizations; Python gets upset if you mutate interned strings...

Armin is on the case...

Cheers, mwh
