Multiple constexpr bugs

Hello,

The following program doesn't compile with icpc version 15.0.1 but compiles fine with clang++ 3.5 and g++ 4.9.2:

#include <iostream>
#include <type_traits>

template<class K>
class Bar {
    public:
        typedef K type;
};

template<class K>
class Foo {
    public:
        static constexpr const char* const foobar = std::is_same<K, typename Bar<K>::type>::value ? "yo" : "lo";
};

Searching for a workaround on the web, it looks like the following bug is still present with icpc version 15.0.1: http://stackoverflow.com/questions/22540153/intel-icpc-constexpr (compiles fine with clang++ 3.5 and g++ 4.9.2).

Could you please confirm that you can reproduce both bugs ? If so, could you figure out a work around please ?

Thank you for looking.
