Fix a bug that can cause a crash when sub-interpreters use "basic" single-phase extension modules. Shared objects could refer to PyGC_Head nodes that had been freed as part of interpreter shutdown.

  • Issue: CPython 3.12 embedded in WeeChat causes segfault on subsequent calls to Py_EndInterpreter #116510

Sorry, something went wrong.
