Chrome crash

[albertjan]

On version 46.0.2490.86 (64-bit) on mac when I run the tests the tab dies.

On chrome canary version 49.0.2575.0 canary (64-bit) on the same machine it works.

I've debugged it a bit. And when you slowly step through the code it works but as soon as I remove the breakpoints from the amsjs code and "let'r rip" as they say the tab dies.

But as it seem in about 3 months it'll be fixed 😄
