[Eduardo Morales]

New submission from Eduardo Morales :

Running on MacOS Monterrey throws following error:

```malloc: *** error for object 0x7ffb5ea1a120: pointer being freed was not 
allocatedPython(4899,0x1061a8600)```

This started happening right after upgrading to the new MacOS Beta.

I am not sure how to reproduce it, I think it's being caused by an imported 
library.

I've been able to tackle the issue down and reported it to the library. 
Although I'm not sure if it's a Python or library issue.

Not sure if this is helpful, but I am attaching the MacOS bug log that is
