[Bug objc/35996] ICE while building simple ObjC code with -fobjc-gc

I'm not sure that's the case, as I've taken a look at the gcc libobjc code, and
it does seem to have some support for boehm GC integration. For example, a
fragment of code from gcc-4.2.3/libobjc/objects.c runs as follows:

#if OBJC_WITH_GC
  if (CLS_ISCLASS (class))
    new = (id) GC_malloc_explicitly_typed (class->instance_size,
                                           class->gc_object_type);
#else
  if (CLS_ISCLASS (class))
    new = (*_objc_object_alloc) (class);
#endif

Of course, perhaps that's just preliminary code for support in some future
version, and the vanilla gcc runtime doesn't support --enable-objc-gc. But if
that's so, there's still the question of why it ICEs on x86-64 but not on x86.
And also of the info page 7.3 regarding garbage collection in the GNU (not
NeXT) runtime.
