Reproduction Steps:
1- Open reproduction project and build for WebGL (Make sure WebAssembly is enabled).
2- Run the build using a WebAssembly enabled browser.
3- Click on "Play" button.
4- Set pitch value to 0 using InputField or Slider.
5- Click on "Apply Pitch" button.

Expected Result: Pitch value changes to 0.
Observed Result: Build crashes with a message, "Uncaught RuntimeError: integer result unrepresentable".

Reproduced with: 2017.1.0a3, 5.6.0f1

-Same crash happens when you increase pitch value to something high (e.g. 15), apply it, then reduce it to 1 and apply again.
