To reproduce:
1) Open attached project
2) Open BasicSetup scene
3) Build and run on WebGL
4) Try to run on Chrome

It fails with this error: http://puu.sh/udeM8/2f00695476.png

This is the console output: http://puu.sh/udeVK/1ff8716bb1.png http://puu.sh/udeUV/86a21661ec.png

Only happens in Chrome 56.0.2924.76 (64-bit).
Doesn't happen in Chrome Incognito mode or Firefox

Reproduced in 5.6.0b1(there instead an "Uncaught Webassembly support is not available on this browser" is thrown), 5.6.0b6, 5.6.0b9
Not reproduced in 5.5.2f1

As Stefan asked, will note that WebAssembly option in Editor is disabled and both webassembly flags in chrome are set to "Default"
