sys._getframe(2) fails in the following example:

code = "from enum import Enum; Enum('Animal', 'ANT BEE CAT DOG')"
code = compile(code, "<string>", "exec")
global_ns = {}
local_ls = {}
exec(code, global_ns, local_ls)

Error with Python 3.7.2 (Fedora 29):

Traceback (most recent call last):
  File "x.py", line 5, in <module>
    exec(code, global_ns, local_ls)
  File "<string>", line 1, in <module>
  File "/usr/lib64/python3.7/enum.py", line 311, in __call__
    return cls._create_(value, names, module=module, qualname=qualname, type=type, start=start)
  File "/usr/lib64/python3.7/enum.py", line 429, in _create_
    module = sys._getframe(2).f_globals['__name__']
KeyError: '__name__'

The bug has been reported in my perf project:
https://github.com/vstinner/perf/issues/49

Looks like the following code:

        if module is None:
            try:
                module = sys._getframe(2).f_globals['__name__']
            except (AttributeError, ValueError) as exc:
                pass

needs to have `KeyError` added to the `except` line.

Marking this as "easy".  It needs a test showing the failing behavior, then the fix.

Hi, PR https://github.com/python/cpython/pull/11521 should fix the issue.

It's PR 11523.

That PR does not go with this issue.  ;)

It does. You removed the link to PR 11523 which is a fix for this issue.

I was confused with PR, so here you have:

* master: https://github.com/python/cpython/pull/11523
* 3.7: https://github.com/python/cpython/pull/11669

Both are merged, so I close the issue. Thanks Rémi Lapeyre for the fix!
