Re: gnustep compiled with clang and gworkspace problem

[Fred Kiefer]

The segmentation fault you are getting is really worrying. What kind of 
X server are you using? And has this changed since you last used GNUstep?

The pasteboard problem could be caused by a background process that was 
created by a previous compile still running in the background. It could 
well be that clang an gcc result in different method signatures, 
although that is rather undesirable.

The setDelegate_reload is one of the tests I expect to fail.
