Re: deallocating None issue with connect/disconnect

[Marko Smej]

I have a similar issue using the Python MySQL connector, but only with the latest version, 8.0.33.

After downgrading to 8.0.32, everything works as expected.

Happens on any Python version I have tested, from 3.9 to 3.11.

Below is the error from the logs:


Fatal Python error: none_dealloc: deallocating None: bug likely caused by a refcount error in a C extension
Python runtime state: initialized
