Hi,
with my adventures on getting gnustep to work on the sparc64 OpenBSD platform,
and even with the warnings I still get with -base, I thought I compile a couple
of apps, and try how it works. However, all segfault in the same spot in
gnustep-back, below an example of Affiche. I use gnustep from svn, together
with libobjc2, using cairo backend.
(gdb) r
Starting program: /usr/local/bin/Affiche
2011-11-03 18:06:17.840 Affiche[26421] Did not find correct version of backend
(libgnustep-back-020.bundle), falling back to std (libgnustep-back.bundle).
Program received signal SIGSEGV, Segmentation fault.
