           Summary: a not-useful non-avoidable warning:  conversion to a
                    reference to the same type will never use a type
                    conversion operator
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: serge.bogdanov@intel.com
                CC: gcc-bugs@gcc.gnu.org

Warning: "conversion to a reference to the same type will never use a type
conversion operator" is generated in decl.c:12578.

It would be nice to be able to turn the warning off or get rid of it, because it
does not provide any useful info.

This warning is produced in the following example (that shows a possible usage
for the conversion operator):

#include <iostream>
struct X;
struct A {
    virtual operator X&();
};
struct X : public A {
    operator X&() {
	return *this;
    }
};
A::operator X&() {
    static X x;
    std::cerr << "Error" << std::endl;
    return x;
}
