[Bug c++/17938] New: cannot assign result to const reference if copy ctor is not accessible

[bryner at brianryner dot com]

This code fails to compile on current mainline:

-------------
class A
{
  A(const A&);
};
 
const A GetA();
 
void caller()
{
  const A& a = GetA();
}
-----------------------------

with this error:

access-const-ref.cpp: In function `void caller()':
access-const-ref.cpp:3: error: 'A::A(const A&)' is private
access-const-ref.cpp:10: error: within this context

It compiles fine on gcc 3.3.3.  compiler version:
