So this is getting off track—but I've been able to isolate the problem.
It occurs when trying to initalize an Array or a Set inside the function
`_gnu_process_args` of `NSProcessInfo.m`
Here is a printf debugging transcript of mine:
Starting NSApplication main.
Inside NSApplicationMain(argc,argv)
Will create autorelease pool...
Running NSObject self

Inside _gnu_process_args.
Checking for argv
Processing argv into NSMutableSet.
Will crete gnu_arguments - have added 1

GNUSTEP Internal Error:
The private GNUstep function to establish the argv and environment
variables was not called.
Mismatched library versions between GNUstep Foundation (base) and AppKit
(gui) is most often the cause of this message. Please be sure you
are using known compatible versions and not a mismatched set. Generally,
we recommend you use versions of base and gui which were released together.
For more detailed assistance, please report the error to [email protected].
It's very odd that this would crash. Totally perplexed and in the weeds here :(
