I get this warning when I compile python without the --with-pydebug flag.


Python/pylifecycle.c: In function 'Py_NewInterpreter':
Python/pylifecycle.c:1442:12: warning: 'tstate' may be used uninitialized in this function [-Wmaybe-uninitialized]
     return tstate;
            ^~~~~~

Does not occur with python 3.7
