There was a weird bug that took me forever to debug… and in the end, it was caused by some horrible bug in some map structure (NSDictionary? I think?) where a NSString unicode key did not map to the same value every time. Quite basic stuff. (It worked fine on Mac.)
As a student I didn’t really know how to report bugs, so I didn’t; I just wondered how did nobody catch it until now; but I just thought that probably nobody really uses GNUStep so that’s why.
It’s just anecdotal and I don’t really have access to the code anymore so I cannot tell you the details. (the original code was far from perfect too, maybe it was some unicode weirdness.)
