描述

Required prerequisites

What version (or hash if on master) of pybind11 are you using?

2.10.2

Problem description

We want to upgrade from pybind11 release 2.9.0 to 2.10.2, but we encountered an issue in the Python atexit (https://docs.python.org/3/library/atexit.html) functions, that our custom types are not registered anymore. With delta debugging we found that this PR caused the issue: https://github.com/pybind/pybind11/pull/3744

In my opinion the

    detail::get_local_internals().registered_types_cpp.clear();    
    detail::get_local_internals().registered_exception_translators.clear();

calls should be after the Py_Finalize function call.

When I change the orders of those function calls, the problem is gone.

Reproducible example code

No response

Is this a regression? Put the last known working version here if it is.

2.9.1
