  #include <iostream>

class Data
{
	 int d_x;

public:
	constexpr Data(int x):d_x(x)
	{}

	int constexpr cMember()
	{
		return d_x;
	}

	int member() const
	{
		return d_x;
	}
};

int main(){                     

	constexpr Data d2(0);  

	enum e2 {
		OK = d2.cMember(),   
	};
	std::cout<<OK;
}


Is it a bug in visual studio??

Which version of VS? VS does not support constexpr yet: http://msdn.microsoft.com/en-us/library/vstudio/hh567368.aspx

Partial? support for constexpr was added in November 2013 CTP
