I guess it depends on the meaning of "obtained".  If "obtained" refers to the
form of the expression, G++ is following the standard.  If it refers to the
place where the pointer was originally turned into a glvalue, then G++ is
wrong.

I think the best thing to do is to stop looking specifically at the form of the
expression and instead see if the address of the expression is null.
