Crash report

What happened?

Using 3.13b4 and main (5592399):

$ Programs/_testembed test_repeated_init_exec 'import ssl' --- Loop #1 --- --- Loop #2 --- Segmentation fault (core dumped) 

Using 3.12:

$ Programs/_testembed test_repeated_init_exec 'import ssl' --- Loop #1 --- --- Loop #2 --- _testembed: Python/getargs.c:2052: parser_init: Assertion `parser->kwtuple != NULL' failed. Aborted (core dumped) 

The 3.12 output implies a problem related to argument clinic and the kwarg names tuple that gets cached.
