New submission from Oren Milman:
on Windows, assuming the file 'foo.zip' exists, the following would cause an
assertion failure in Modules/zipimport.c in
zipimport_zipimporter_get_data_impl():
import zipimport
class BadStr(str):
def replace(self, old, new):
return 42
zipimport.zipimporter('foo.zip').get_data(BadStr('bar'))
this is because zipimport_zipimporter_get_data_impl() assumes that
BadStr('bar').replace('/', '\\') is a string.
