WebThread JavaScriptCore crash - what this crash report means

Question

I need help in understanding this crash log from a test user. I did not write any JavaScriptCore related code in my app.

I still don\'t know how to reproduce this

Answer 1

This crash is a result of bug in WebKit. It was fixed at 06/05/15. iOS 9 was released at 09/09/15, so most probably this bug is already fixed in last iOS version. Although it still affects iOS 8, and there is no straightforward workaround.
