I just don't think anyone's ever bothered to catch this case.  I believe
there is a BZ which touches on this issue.

Yes, here it is: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78655

This PR uses a placement new as the example, which in GCC 8 assumes the 
pointer argument to `operator new()` is never null. But for a general 
case it is still not fixed.

So it looks like nobody has been working on this. I will just fix my 
code then.
