Hi All,

on a fairly reliable Linunx system, configured standard (no special options to base) no GUI app is capable to start. However simple tools like "plparse" runs. This situation happened since I updated libobjc2 to latest and all the rest of GNUstep too.

This configuration should use the "gnu" runtime mode, if I understand correctly.

I am not sure if the issue is in libobjc2 itself, where the crash happens or not.
A similar configuration on FreeBSD; I have issues too, but different.

Does the stacktrace tell you something useful?how to get more information?

Thanks

Riccardo
