This works fine in dmd 2.075:

struct A
{
     this(string a) {}
     this(string a) shared {}

     ~this() {}

     this(this T)(this) {} // you can reflect to find out if shared
}

void main()
{
     auto nonShared = A("");
     auto shared_ = shared A("");
     auto nonSharedCopy = nonShared;
     auto sharedCopy = shared_;
}
