I have detected 3 memory leaks when I execute python -V with valgrind -> 162 bytes. The leaks do seem to be in pymain_init and in _PyPreConfig_ReadFromArgv (the string for the locale is not freed). Also _PyRuntimeState_Fini does not release the memory of the mutex on runtime->xidregistry. You can find the first status in the valgrind.log file (with the leaks). |

@vstinner I ping you because you are the main author for the new changes in the interpreter and the PyPreConfig part. |

I assign the issue to myself, since I'm currently working on the code: bpo-36301. |

I close the PR 12389 because it superseded by PR 12400 (only the fix for _PyRuntimeState_Fini). |

"./python -V" no longer leaks, so I close the issue. See bpo-36356 for the follow-up. |
