> The problem is resolved if call PyGC_Collect() after PyDict_DelItemString(). Is it expected to call PyGC_Collect() here?

Yeah sadly, to handle such reference cycles, you have to trigger an explicit garbage collection.

It doesn't sound like a bug to me.

Python 3.4 made this way better with PEP 442.

Anyway, that's an old issue with no activity since 2016. I close it.
