Code Sketch - Newtime.jstalk example crashes

[kjk]

I'm running Cocoa Script Editor from inside XCode 5.0.2 on OS X 10.9.1

Simply running Code Sketch - Newtime.jstalk example crashes after a couple of seconds.

The callstack:

I'm seeing that too. Lots of stuff changed in JS for 10.9, looks like it's biting me.

Well, it no longer crashes - but it will if you try and print anything out in the draw function. I'm not sure why yet though… something tells me it's a race condition with GC.
