[Bug c++/26191] New: temporary is not bound to non-const reference

[istvan dot benedek dot ext at deutsche-boerse dot com]

I expect the following snippet to compile without errors (even a warning(s)
should be parametrized).

As stated in [class.temporary]/5, the temporaries can be bound to non-const
references too...

struct A {};

A fct() { return A(); }

int main(int, char**)
{
  const A& aConstRef = fct(); // compiles: temporary bound to const reference
  A& aRef = fct();            // error: temporary bound to non-const reference

  return 0;
}

I called g++ wo. parameters [sparc-sun-solaris2.8].

------- Comment #1 from bangerth at dealii dot org  2006-02-15 19:45 -------
The clause you cite only deals with the lifetime of temporaries, not with
the question whether they can be bound to references in the first place.

8.5.3/5 states that references can only be bound to lvalues or, if they
are rvalues only to constant references.
