Clang gives a very similar result, so I'm not convinced it's a bug:

t.cc:12:2: error: call to 'horizontalConcat' is ambiguous
 horizontalConcat({a,b});
 ^~~~~~~~~~~~~~~~
t.cc:6:8: note: candidate function
Matrix horizontalConcat(const std::vector<Vector>& vectors);
       ^
t.cc:7:8: note: candidate function
Matrix horizontalConcat(const std::vector<Matrix>& matrices);
       ^
