Re: [chromium-discuss] Which one of these flag causes click bookmark star in omnibox to crash Chromium?

[K. Moon]

If it's due to an experiment, you can try using the https://chromium.googlesource.com/chromium/src/+/main/tools/variations/bisect_variations.py tool. Otherwise, you really should be reporting this as a crash bug; there's no reasonable way to diagnose a crash with this little information.

I'm running Chromium Developer Build from https://download-chromium.appspot.com/ 

> This is a raw build of Chromium for Linux x64, right off the trunk. It may be tremendously buggy.

Reading the latest https://peter.sh/experiments/chromium-command-line-switches/ I noticed --disable-sync was not (no longer apparently) an option. Bookmarks works now. I have no idea why --disable-sync then trying to set a bookmark either using star in address bar or context menu bookmark this tab option crashed (closed the application) Chromium. Just a peculiar crash on a UI component corresponding to a specific flag.

Chromium authors banned me from contributing on chromium.org.
