This issue is a duplicate of bpo-44434 which has been fixed.

I created PR 26943 based on Alexey's PR 24241 to complete my fix.

Alexey Izbyshev  added the comment:

Thank you for testing. I've added a NEWS entry to the PR, so it's ready for 
review by the core devs.

Note that PyThread_exit_thread() can still be called by daemon threads if they 
try to take the GIL after Py_Finalize(), and also via C APIs like 
PyEval_RestoreThreads() (see bpo-42969), so, in general, libgcc_s is still 
required for CPython.

I think the crash is fixed by this PR. I try other arguments. No crash is

I've made a PR to remove most calls to pthread_exit().

@xxm: could you test it in your environment?
