[Bug c++/65945] C++ alignment of nullptr_t is 1 and might cause unaligned stores to the frame

--- Comment #5 from npl at chello dot at ---
making nullptr_t "similar" to void* would sound very reasonable to me. I tested
clang and it seems to behave that way.

Whatever the C++ ABI group comes up with, the unaligned accesses have to be
fixed. This was really annoying to track down, as the stores will only be
generated without optimizations - in other words I was searching for a
completely different bug.

I searched the bug database and supposedly throwing and catching nullptr`s is
something legal. So you will have to correctly align it anyway, even if its
arguable if nullptrs should ever be explicitly stored.
