Thanks for filing the issue.
Could you please provide us the crash report id from chrome://crashes to triage the issue further.

Sorry, I'm not sure I can - Ubuntu Chromium build has crash reports disabled. Quoting my Chromium:

Crash reporting is disabled.
Crash reporting is not available in Chromium.

However, I've reported the crash into the launchpad as well: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1763765

Seems it is out of scope from TE end (as it build relates issue), adding TE-NeedsTraige-help label to move this out of our triaging bucket.

Could someone from dev team please take a look into this issue.
Thanks..!
Can you debug it as per: https://wiki.ubuntu.com/Chromium/Debugging

And provide a stack trace?
I will try, thank you. However meanwhile this stack-trace may help?

Pasting the follow-up discussion here:

Q: Is bitbucket pipeline log known to be memory-hungry?

A: Yes, the log may get quite long, in my case it is a 8,5 megabytes long txt file.

Generally bitbucket pipeline runs a (maven)-based build after every git commit, and you can watch the particular pipeline web page to watch the log unwind as the build progresses. The thing is, when you open a finished pipeline, Chromium has no trouble displaying page with a 8,5MB log. However, when you start the pipeline and watch the log progress from zero, Chromium will eventually crash well before the log hits, say, 1MB. So I'd assume it's the refreshing of that particular page which brings Chromium down.

This sounds like it is a javascript memory leak in the buildbucket code. You should try to take memory snapshots in the developer tools and see if any of your JS code is leaking memory.
