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.
