1. This code print error (that is OK):

struct Test{   /////Error: struct Test may not define both a rvalue constructor and a copy constructor

    this(ref const typeof(this) rhs){
    }

    this(const typeof(this) rhs){
    }
}

void main(){
    const Test cb;
    Test b = cb;
}


2. This code crash DMD:

struct Test{

    this(ref const typeof(this) rhs){
    }

    this()(const typeof(this) rhs){   ///<-- rvalue ctor is template
    }
}

void main(){
    const Test cb;
    Test b = cb;
}
