This is failing a compile time assertion:

  // Ensures that argument #k is a reference.  If you get a compiler
  // error on the next line, you are using SetArgReferee<k>(value) in
  // a mock function whose k-th (0-based) argument is not a reference.
  GTEST_COMPILE_ASSERT_(internal::is_reference<argk_type>::value,
                        SetArgReferee_must_be_used_with_a_reference_argument);

The problem is that argument 1 (0-based) is not a reference.

I wonder why the compiler is not showing SetArgReferee_must_be_used_with_a_reference_argument in the error.

Hope this helps,

_Sam
