Here's the simplest example I could come up with -- hit this while debugging pytest (which uses attrs which uses similar code to this to make classes)

import pdb; pdb.Pdb(skip=['django.*']).set_trace()
eval(compile("1", "", "exec"), {})

When running this:

$ python3.8
> /home/asottile/workspace/setup-cfg-fmt/<module>()
-> eval(compile("1", "", "exec"), {})
(Pdb) n
Traceback (most recent call last):

    eval(compile("1", "", "exec"), {})

    return self.dispatch_call(frame, arg)

Thanks @blueyed, I guess the backport was not made by the bot though the label was applied for 3.7 branch.
