We have an ImpactJS-based HTML5 (canvas) game which, since iOS8 update, seems to happen quite often with an error. We tried it in a UIWebView-based shell, and everything seems to be in order. In the WKWebView shell, we get crashes the same as in Safari.
Crash logs don't show much (or at least I don't know how to extract anything useful from them), but the type of exception is EXC_BAD_ACCESS (SIGSEGV) with a subtype of KERN_INVALID_ADDRESS at 0x0000000000000000.
I am really at a loss why he is falling. The game works great in older versions of Mobile Safari and is great for Android.
How can I solve this, or if it fails, are there any methods that I can use to narrow down the question from which the problem arises?
