SIGSEGV (Address boundary error) when trying to import plist with python #187

Open James-Hudson3010 opened 3 years ago

James-Hudson3010 commented 3 years ago

I built libplist with the python bindings and when I try to import it, it crashes.

My simple script is:

import sys
sys.path.append( "/Users/jamesh/tmp/local/lib/python3.8/site-packages" )
import plist

without the path append, python tells me the module is not found.

to create the Makefile, I used ./autogen.sh --prefix=/Users/jamesh/tmp/local --enable-debug

A crash report is generated:
