The following well-formed code cannot be compiled with clang-trunk and the
-std=c++11 (and -std=c++14) flags.
template<typename T>
int f(T x)
{
return x.get();
}
template<typename T>
constexpr int g(T x)
{
return x.get();
}
int main() {
// O.K. The body of `f' is not required.
decltype(f(0)) a;
// Seems to instantiate the body of `g'
// and results in an error.
decltype(g(0)) b;
return 0;
