[New-bugs-announce] [issue26558] Fix PyGILState_Check() with _testcapi.run_in_subinterp()

[STINNER Victor]

New submission from STINNER Victor:

assert(PyGILState_Check()) cannot be used in functions called by Py_NewInterpreter(): the assertion fails.

I propose to add a flag to disable PyGILState_Check() while Py_NewInterpreter() is run to be able to add assertions in these functions.

The assertion helps to detect complex bugs like race condition in multithreaded applications.
