I don't know, but if you do
while 1:
test_contextlib.test_main()
gc.collect()
under a debug build it eventually (> 500 iterations) crashes with
Fatal Python error: deallocating None
That's a pretty good clue ;-) The
Py_XDECREF(gen->gi_frame);
in gen_dealloc() is on the call stack at the time, and cyclic gc is active.
