c++ - Const confusion

The following code:

class X
{
public:
    operator char const * const() const;
    operator char * const();

};


int main(int /* argc */, char ** /*argv*/)
{
    X           x;
    char const  *pc     =   x;

    return 0;
};

gives the error:

    char const  *pc     =   x;
                             ^
h:\dev\test\compiler\dm\xsconst\xsconst.cpp(17) : Error: need explicit cast
to convert
from: X
to  : char const *
--- errorlevel 1

Removing the second const, which is the unnecessary one, from the first line
corrects the confusion. This is a bug with both 8.28 and 8.30.3

The other two I posted at the same time have been resolved, so wondering
whether this one gone under your radar?
