PUN + WebGL crash with Unity 5.3.1f1

Reisender

I recently upgraded from Unity 5.2.3f1 to 5.3.1f1 and rebuilt a project using PUN. As soon as the scene using PUN is started, the browser throws and exception and the game stops:

An error occured running the Unity content on this page. See your browser's JavaScript console for more info. The error was: Uncaught abort(157) at Error at jsStackTrace (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:1270:13) at stackTrace (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:1287:22) at abort (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:4724456:44) at nullFunc_ii (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:16587:464) at Array.b157 (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:4718125:32) at __Z24SetPlayerRunInBackgroundb [SetPlayerRunInBackground(bool)] (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:892254:36) at Array.__Z42Application_Set_Custom_PropRunInBackgroundh [Application_Set_Custom_PropRunInBackground(unsigned char)] (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:1017064:2) at _Application_set_runInBackground_m_1961756033_0 (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:3845571:30) at Array._PhotonNetwork__cctor_m339060500_0 (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:2642439:2) at Array.__Z33RuntimeInvoker_Void_t_224166001_0PK10MethodInfoPvPS2_ [RuntimeInvoker_Void_t_224166001_0?2(void**, undefined?S?*)] (blob:http%3A//localhost/81467601-459e-4f41-9086-30790833fc7b:4542841:32)

This is what the javascript console prints:

Invalid function pointer called with signature 'ii'. Perhaps this is an invalid value (e.g. caused by calling a virtual method on a NULL pointer)?

BTW I'm using PUN Free v1.65.

Though I purchased PUN+ from the photonengine.com site, I haven't been able to download the PUN+ package.

Looks like same issue?

Sort of...

Indeed, Application.runInBackground makes the game crash. As I said before, this didn't use to happen with previous versions of Unity.

I've found that unchecking Strip Engine Code fixes the crash, though it will make builds much larger. This bug has been fixed in Unity 5.3.1p2 http://unity3d.com/unity/qa/patch-releases
