Crashes on Mac OS X 10.12.2

[JadedEvan]

Hello!

I've been very interested in seeing how rust is used for game development as an opportunity to learn more about the language. When attempting to compile and run this program I get a pretty nasty crash. Before I spend some time trying to dig this apart - I'm wondering if any of the following might look familiar to you:

Thanks for your feedback!! I have no Mac OS to check but this seem to be a problem with Rust or Piston itself (I prefer Rust). Btw, I've replaced all unwrap() with expect() in my code. You should check it again to see if there is any difference or not.

Thanks for the quick reply.

I just saw these changes on master. I pull those in, still getting a crash.
