Thank you for the report! This is currently tracked internally by Apple as <rdar://problem/21589337>. This is an issue in a system framework below WebKit, so we cannot track it here, marking as INVALID. However, please let us know if you have any additional information beyond the crash logs. Are you aware of any websites where this happens more or less reproducibly? Any other hints for re-creating this crash?
