Minimal example

A rather simple program using C++ exceptions in Objective-C++ can generate an
ICE.

exceptionice.mm: In function 'void Problem()':
exceptionice.mm:1:6: internal compiler error: in objc_eh_runtime_type, at
objc/objc-next-runtime-abi-01.c:2804
 void Problem()
      ^

Compiled on Mac OS X 10.4 on a PowerMac G4 with the following configuration:

CC=gcc-4.2 CXX=g++-4.2 AS=/opt/cctools/usr/bin/as
AS_FOR_TARGET=/opt/cctools/usr/bin/as ../GCC/configure --prefix=/opt/gcc/5
--disable-nls --enable-languages=c,c++,objc,obj-c++,lto --disable-multilib
--with-dwarf2

Command line used to get the error is:

/opt/gcc/5/bin/g++ exceptionice.mm
