     Type:  defect                             |     Status:  new
 Priority:  Normal                             |  Milestone:
Component:  ports                              |    Version:  2.7.1
 Keywords:  python 3.8, crash, c type pointer  |       Port:  python38
-----------------------------------------------+----------------------
 On our testing, we encounter an abort crash at the end of execution when a
 c pointer is assigned to a variable. We are able to replicate it using
 sample code from:

 https://docs.python.org/3/library/ctypes.html
 {{{
 import ctypes as C
 from ctypes import *
 def py_cmp_func(a, b):
     print("py_cmp_func", a0, b0)
     return 0
 CMPFUNC = CFUNCTYPE, POINTER)
 cmp_func = CMPFUNC
 }}}
 Abort occurs after this code is run.

 We did not encounter this issue using code above on:

 1. Python 3.8.12 using OSX 10.12
 2. Python 3.8.10 using OSX 10.15.1
 3. Python 3.9.10 using OSX 10.15.1
 4. Python 3.10.1 using OSX 10.15.1
 5. Latest Python 3.2-3.7 using OSX 10.15.1

 Mac ports was used for installing and setting up Python versions.

 Attached is the log generated by OSX 10.15.

 Issue only occurs on iMac 21.5 Late 2015 using Python 3.8.12 on OSX
 10.15.1.

 I tested on iMac 21.5 Late 2009 using Python 3.8.12 (Installed by Mac
 Ports) on OSX 10.12.6 and crash was not encountered.

 We checked using homebrew pyenv's Python 3.8.12 (Python does not provide
 PKG for 3.8.12 and PyEnv built from source) and crash does not occur. We
 think that maybe the installer used for Python 3.8.12 on Mac Ports has an
 issue with 10.15.1.
