[issue40413] Py_RunMain() crashes on subsequence call

Gregory Szorc added the comment: I can't remember the circumstances of me reproducing this. The added test demonstrating that the interpreter can be initialized/finalized within a single process seems like a reasonable solution to ensure this is supported. -- ___

[issue40413] Py_RunMain() crashes on subsequence call

STINNER Victor added the comment: I never tried, but I expect that the following pattern is fine: for (i=0; i<5; i++) { Py_Initialize(); Py_RunMain() } Maybe Py_RunMain() must fail with a fatal error if it's called when Python is not initialized. Since Py_RunMain() finalizes Python, you

[issue40413] Py_RunMain() crashes on subsequence call

Gregory Szorc added the comment: Actually, I can reproduce the crash without Py_RunMain(). So I don't think the crash is related to the additional cleanup that Py_RunMain() does in addition to Py_FinalizeEx(). But I'd like to keep this issue open to track the original question about expecte

New submission from Gregory Szorc : I'm attempting to perform the following actions multiple times in a single process with CPython 3.8.2: 1) Initialize an interpreter using the PEP-587 APIs. 2) Call Py_RunMain() (which finalizes the interpreter). However, I've encountered at least 2 crashes
