All the snippets are rejected in mainline (would be 4.7), all but Comment 3 in
4.6.x too.

------- Comment #3 from dibeas at ieee dot org 2010-02-08 12:11 -------
Also related: dereferencing a data member pointer with an lvalue incorrectly
yields an lvalue:
struct X { int x; };
X f();
void g() {
int X::*ptr = &X::x;
f().*ptr = 5; // should not compile!
}

------- Additional Comments From bangerth at dealii dot org 2004-05-05 01:24 -------
Confirmed. We don't even give a warning about taking the
address of a temporary :-(
This is what I get from icc:
g/x> icc -Xc -ansi -c x.cc
x.cc(9): warning #592: variable "a" is used before its value is set
return a;
^
x.cc(14): error: expression must be an lvalue or a function designator
int* p = &f().a; // should reject as rvalue.field is still an rvalue
^
compilation aborted for x.cc (code 2)
W.
