Do you get crash reports in /var/crash ?
Is this a regression (i.e. were you observing the same crashes with previous versions of chromium-browser)?
Is the latest update (63.0.3239.84-0ubuntu0.17.10.1) also affected?
Do you know what triggers the crash (e.g. loading a certain type of web content, …)?

> Do you know what triggers the crash (e.g. loading a certain type of web content, …)?
No. And so cannot try reproducing with other versions or proprietary Chrome.

I did not see them. But as I met those segfaults very rarely, may be new ones will still happen one day.

> Do you get crash reports in /var/crash ?
Will look for them a bit later if they were there and have not been deleted.

Ubuntu 17.10 (artful) reached end-of-life on July 19, 2018

@mikhailnov, presumably you have now upgraded Ubuntu to either Ubuntu 18.04 or Ubuntu 18.10. Do you still see random crashes with the later Ubuntu and Chromium releases?

[Mikhail Novosyolov (mikhailnov)]

No, it does not crash unless there is no disk space left. Closing.

Thanks for the feedback. Marking fixed per last comment.
