[issue40965] Segfault when importing unittest module

[The Comet]

New submission from The Comet :

The following program will segfault the interpreter:

#include 
int main() {
Py_Initialize();
PyRun_SimpleString("import unittest");
Py_Finalize();

Py_Initialize();
PyRun_SimpleString("import unittest");  /* segfault here */
Py_Finalize();
}

This only seems to happen with the unittest module. This is something that used 
to work but broke somewhere between python 3.7 and 3.8.

The code above can also be found on github as a cmake project for your 
convenience:

[issue40965] Segfault when importing unittest module via C API

The Comet  added the comment:

Thanks for the input! I should have been more specific. I was running python 
3.8.2 when I got this segfault.

I upgraded to 3.8.3 and the issue is no longer present, so it seems this has 
already been fixed.
