STINNER Victor added the comment: I tested my fix manually using example from msg350262 and gcc -O3 (./configure && make): I can reproduce the crash without the change, and I confirm that my change fix the crash. Thanks Miro for the bug report: the fix will be included in next Python 3.8

New submission from Miro Hrončok : There is a regression between Python 3.7 and 3.8 when using PySys_SetArgvEx(0, NULL, 0). Consider this example: #include int main() { Py_Initialize(); PySys_SetArgvEx(0, NULL, 0); /* HERE */ PyRun_SimpleString("from time import time,ctime\n"
