[issue33720] test_marshal: crash in Python 3.7b5 on Windows 10

The uploaded binary is compiled with PGO enabled (and trained on most of the test suite). I'll check it out - hopefully we don't need to do anything drastic and can get away with either a compiler update or disabling optimizations on a single function.
