WebGL Freeze logfile

I'm experiencing a freeze of the browser (chrome, ff, safari) when I run a non-development WebGL build of my project. I have to "force quit" it, so I can't access the js console to figure out what's happening – Is there a logfile I could look at somewhere outside the browser?

Is it actually possible to connect the debugger to webgl? If it is, it doesn't work for me.

Unfortunately a bug snuck in, in which we omit needed information from release builds. We fixed this and it has landed for one of the following betas.

Missing information is managed stack sentry, so anything that uses the callstack (this can be internal calls for corlib) can get into an infinite loop.

Ok, great!
