This issue looks like a bug in Flask or a C extension used by your application. You should try to debug it with gdb. Or at least try to get a Python traceback: https://pythondev.readthedocs.io/debug_tools.html#get-a-traceback-on-a-crash You should specify your Python version, OS and OS version, explain how to reproduce the crash, etc. |

I close the issue. It's a bug in a third-party project, not in Python itself. If you can reproduce the bug with a simple script which only uses the stdlib, please reopen the issue. |
