Demonstration of ICE on VS 15.5 Preview 2

ice_vs_15.5_prev2.cpp

//This code causes an internal compiler error on visual studio 15.5 preview 2's version of MSVC

#include <math.h>
#include <utility>

struct Vector3 final
{
	float x, y, z;
};

template <class... VV>
inline Vector3 Min(const Vector3& a, const Vector3& b, VV&&... c) noexcept
{
	if constexpr (sizeof...(VV) == 0)
		return { std::min(a.x, b.x), std::min(a.y, b.y), std::min(a.z, b.z) };
	else
		return Min(Min(a, b), std::forward<VV>(c)...);
}

int main()
{
	Vector3 a{ 0.2f, 0.1f, 7.0f };
	Vector3 b{ 0.7f, 0.8f, 0.0f };
	Vector3 c{ 0.9f, 0.2f, 9.0f };
	Min(a, b, c);

	return 0;
}

This works with a more recent compiler build: Microsoft (R) C/C++ Optimizing Compiler Version 19.11.25902 for x86

Note you need to include <algorithm>.
