Are you meant to do anything magic to make the pointers that you pass to llvm_eh_selector() PIC-aware?  The code works if I modify the generated assembly and changing that line to:

Is there any work around that I can use?  GNUstep Make passes -fPIC by default, so this causes any GNUstep code containing @catch blocks with any type other than id to crash when compiled with clang.

Note that this happens for me on IA32 as well as x86-64 - everything in the bug report seems to be x86-64 specific.
