No, your example 2 would mean "xr is a pointer to a char reference".
Your example 1 is what you want, is legal, and should work -- "xr is
a reference to a char*".  It does work on two compilers I tried,
Oregon C++ and Turbo C++.  It sounds like the compiler you are using
needs fixing.  (Or maybe there is an error in your coding which
doesn't show in this question.)
