<pre>Clang++ rejects the valid code as ambiguous, while g++ accepts:
$ cat s.C
template<typename T, typename U> void f(U&) { }
template<typename T, typename U> void f(T const&) { }
int main()
{
int a;
f<int, int const>(a);
}
$ clang++ -c s.C
s.C:6:5: error: call to 'f' is ambiguous
f<int, int const>(a);
^~~~~~~~~~~~~~~~~
s.C:1:39: note: candidate function [with T = int, U = const int]
template<typename T, typename U> void f(U&) { }
^
s.C:2:39: note: candidate function [with T = int, U = const int]
template<typename T, typename U> void f(T const&) { }
^
