Subject: Re:   New: a const member function can call a non_const member
function without const_cast

"hongleij at 126 dot com" <gcc-bugzilla@gcc.gnu.org> writes:

| //const_test.cpp
| struct A

|   A(unsigned int n)
|   {
|      aa=n;

|   {
|       static_cast<A>(*this).fun();  //ok

yes, as mandated by C++ semantics -- the static_cast creates a
new object to which fun() is applied.  That is OK.

|      // fun();       //err  

direct call to fun() is an error.

So, this PR does not report an error.  It should be closed as "mistaken".
