So, referenceCount needs to be in any case nuked from struct __cxa_exception.
IMHO, either we define (probably in a different namespace)
struct __cxa_exception_with_refcount
{
_Atomic_word referenceCount;
struct __cxa_exception exc;
};
and corresponding __get_exception_header_with_refcount_from_{obj,ue}
and use this one where needed (at least in eh_alloc.c, eh_ptr.cc and
eh_throw.cc), or we just allocate space for one _Atomic_word before the struct
(i.e. allocate extra MAX (__alignof__ (__cxa_exception), sizeof (_Atomic_word))
before it) and use a macro (and or inline) to get address of referenceCount
_Atomic_word before the __cxa_exception struct.
