Description Antoine Brodin freebsd_committer freebsd_triage 2019-12-10 13:44:29 UTC 
It seems that sysutils/py-psutil Process is broken on 12.0+ i386  (this code runs fine on 11.3 i386 or on amd64)

Sample code:

root@121i386-custom:~ # python3.6
Python 3.6.9 (default, Dec 10 2019, 09:51:50)
[GCC 4.2.1 Compatible FreeBSD Clang 8.0.1 (tags/RELEASE_801/final 366581)] on freebsd12

>>> import os
>>> import psutil
>>> os.getpid()
19956
>>> psutil.pid_exists(19956)
True
>>> psutil.Process(19956)
Segmentation fault
