[Bug middle-end/21846] New: segfault in fold_binary compiling vpr with -O3

["janis at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Mainline GCC gets a seg fault building SPEC CPU2000 test vpr on
powerpc64-linux with "-m64 -O3" starting with this patch from rakdver
on 20050517:
                                                                                
  http://gcc.gnu.org/ml/gcc-cvs/2005-05/msg00814.html
                                                                                
The seg fault is in fold_binary at fold_const.c:8971.
                                                                                
I'll attach a minimized test case.
