Linux/Clang/Libobjc2 failure part 1 (gnu)

[Riccardo Mottola]

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
