I am able to reproduce this on clang 3.8.0, using latest versions of
everything from Git.
Steps:
- libobjc2 configured with cmake -DCMAKE_INSTALL_PREFIX=/GNUstep ..
- for some reason that now ends up in
/GNUstep/Local/Library/{Headers,Libraries} instead of /GNUstep/include and
/GNUstep/lib like it did when I wrote my old scripts for building
everything from scratch; either way I now need to teach the rest of the
environment how to find it
- export CFLAGS=-I/GNUstep/Local/Library/Headers
CXXFLAGS=-I/GNUstep/Local/Library/Headers
OBJCFLAGS=-I/GNUstep/Local/Library/Headers
LDFLAGS=-L/GNUstep/Local/Library/Libraries
LD_LIBRARY_PATH=-L/GNUstep/Local/Library/Libraries:$LD_LIBRARY_PATH
- configure make with: CC=clang CXX=clang++ OBJC=clang ./configure
--with-layout=gnustep --enable-debug-by-default
--with-library-combo=ng-gnu-gnu --prefix=/GNUstep
--with-config-file=/etc/GNUstep/GNUstep.conf
- my understanding is that ng-gnu-gnu should correctly use the nonfragile
abi, that it should disable mixed abi and all else, so I omitted all that
- install base into system domain after configuring it with: ./configure
--with-ffi-include=/usr/include/`gcc -dumpmachine`
- install gui into system domain after configuring it with: ./configure
--disable-cups
- install back into system domain after configuring it with: ./configure
--enable-graphics=cairo
A bunch of -gui tests fail, and Zcode is failing to start with identical
backtrace.

As far as I can tell, all the important flags have propagated from -make
and do match. Or are they? What am I missing?
I will now rebuild with the gnu-gnu-gnu combo.
