Binding error when overload the constructor

[akineeic]

Hello,

I'm getting an error when trying to overload the constructor of Runtimeshape (class of tflite).

• Environment Info
  OS => Ubuntu 18.04
  Emscripten => fastcomp 1.38.41 or later
  Tensorflow => 1.13

• The binding code

class_<RuntimeShape>("RuntimeShape")
    .constructor<int>(select_overload<RuntimeShape(int)>([](int dimensions_count) {
        return RuntimeShape(dimensions_count);
      }
    ))

• Error message:

            invoker::template invoke<ClassType, Policies...>(callable);
                              ^

I have tested with different version, the bind code works well on version with 1.38.40 but failed with 1.38.41. According to the source code, I found it may caused by the rewrite of emscripten::class_::constructor in this commit. So how should I modify my code to fix the bug?

Thanks.
