Re: Segfault while building PikoPixel

[Gregory Casamento]

GNUstep, very much contrary to popular belief, neither maintains the objc portion of gcc nor does it maintain clang.  If you are getting a segfault while running clang the most expedient place to report any bugs with clang is on their website.

Thanks, GC
