            Bug ID: 37866
           Summary: no matching function for call
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: zhonghao at pku.org.cn

The code sample is as follow:

enum { E = 2 };
template <bool> void f(int) {}
template <int> void f() {}

main ()
 f<1 * 1>();
 f<1 << 1>();
 f<1 ? 3 : 2>();

 f<1 * 1>(0);
 f<1 << 1>(0);
 f<1 ? 3 : 2>(0);

clang++ rejects it with error messages:
error: no matching function for call to 'f'
     f<1 << 1>(0);
error: no matching function for call to 'f'
     f<1 ? 3 : 2>(0);

The code comes from the test suite of gcc

Is this a bug in clang++ or in the test suite of gcc?
