Is this some kind of one-off thing? So we close this as invalid?

[Greg Steuck (Sh-toy-k)]

Looks like some kind of worker state detection misfiring. I'd let it happen at least one more time to maybe notice patterns.

[Anton Lindqvist]

Speaking of invalid, this[1] type of false positive crash should not be
reported anymore[2].

Then reply with "#syz invalid" as per https://goo.gl/tpsmEJ#bug-status-tracking
and it will go away from open bugs.
