Signal 11 caught

About to release on Android, but I’m getting random crashes, where catlog just keeps spitting out ‘Signal 11 caught’ without any reference to where it’s happening. No crash log or dump that I can find either. I’ve been trying to setup debugging for VS2015 but I’ve gotten stuck there as well where the package manager just fails for some reason. Is there any other way I can figure out why this Sig11 is happening? I need to find out asap for releasing.
