It should be basically impossible for the GC to be already collecting garbage at that point... Perhaps you could try to find out in which test this happens?

That's extremely weird. _PyGC_CollectNoFail() is only called from
PyImport_Cleanup, which itself is only called from Py_Finalize()
and Py_EndInterpreter(). It should be basically impossible for the
GC to be already collecting garbage at that point... 

Perhaps you could try to find out in which test this happens?
