[issue31566] assertion failure in _warnings.warn() in case of a bad __name__ global

2017-09-24 Thread Oren Milman 

New submission from Oren Milman:

The following code causes an assertion failure:
__name__ = b'foo'
__file__ = None
import _warnings
_warnings.warn('bar')

This is because setup_context() (in Python/_warnings.c) assumes that __name__
is a string, and so it passes it to _PyUnicode_EqualToASCIIString(), which
asserts it is a string.
