> It could be a problem with the way _Py_RefTotal is incremented/decremented.

It can be a cache which is kept alive and then clear the following iteration. See my previous comment:

test leaked [-4, 4, -4, 4, -4, 4, -4, 4, -4, 4, -4, 4, -4, 4, -4, 4, -4, 4, -4, 4] references, sum=0

libregrtest/ does its best to clear *all* caches, type caches, free lists, etc. A single cache which is not cleared can confused libregrtest.
