Hmmm... let's ignore the possibility to omit the copy for a moment:
the standard defines 'stack unwinding' as (15.2/3)
The process of calling destructors for automatic objects
constructed on the path from a try block to a throw-expression
Does this include the 'argument' of the call expression?
Certainly the expression A() is part of the throw-expression, however
the quote above isn't particularly clear at saying whether "to a
throw-expression" is inclusive or not.
I'm inclined to think that it is inclusive, in principle. Maybe you
know something, from the committee meetings or from the standard, that
contradicts this view?

So I guess :-) The linked to page has, at its bottom, the following
"Series: Lecture Notes in Computer Science. Volume. 1766"
That's itself a link and if you follow it you find a long list with
one of the entries being
"Volume. 1766: Jazayeri, M.; Loos, R. G.K.; Musser, D. R.,
(Eds.) Generic Programming"

Thanks to you :-)
