[issue44869] MacOS Monterrey malloc issue

[Ned Deily]

Ned Deily  added the comment:

The crash report you provide shows a crash in libstdc++ which is normally not 
called directly by the Python interpreter or standard library modules on macOS 
but appears to be being called by libopenblas as provided by the copy of numpy 
in use. Suggest you follow up with the numpy, openblas, or homebrew projects, 
if that's where you obtained numpy and friends. Keep in mind that the problem 
might still be related to the pre-release status of macOS Monterey.  Good luck!

Not sure if this is helpful, but I am attaching the MacOS bug log that is 
auto-generated when Python fails.

There is a 3th possibility: This could be a bug in the OS, Monterey is still in 
beta at this point and beta's tend to contain more bugs than release versions.

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.

Ronald Oussoren  added the comment:

I'm afraid we cannot do a lot with the information you provided. I've just ran 
a full test run for a copy of 3.10rc1 installed using the universal2 installer 
and that doesn't have problem.

One way to find more information about what's going on is to use fault handler 
(e.g. PYTHONFAULTHANDLER=1 python3.10 ...), although that will just print a 
Python stack trace when the executable crashes.

Alternatively use a debugger to look at the C stack.

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

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.
