This is similar to 
https://issues.dlang.org/show_bug.cgi?id=19260, and can be worked 
around the same way by messing manually with the mangled name, if 
you can't adapt the C++ side. The actual problem is that you 
can't express a mutable reference to a const class object (as 
opposed to a struct) in D (`const Y` is a const reference to a 
const Y object).

The Itanium C++ mangling doesn't differentiate between:

void foo(const Y *);       // what you have on the C++ side
void foo(const Y * const); // corresponds to D `void foo(const Y)`
