0.17.7 regression: IntelliSense reports incorrect "no suitable constructor" error

See https://developercommunity.visualstudio.com/content/problem/314489/158-regression-c-intellisense-reports-incorrect-no.html .

template <typename TT>
class Base
{
public:
	Base(const int &rhs) : ss(rhs) { }
	Base(const TT &rhs) : ss(rhs.ss) { }
protected:
	int ss;
};


class cc : public Base<cc>
{
public:
	using Base<cc>::Base;
};
 

int main()
{
	int f;
	cc c = f; // no suitable constructor exists to convert from "int" to "cc"
}

[sean-mcmanus]

Adding this line to "cc" is a workaround (but that workaround is insufficient in more complicated scenarios):

 cc(const cc&) = delete;
