Geoff, do you know what's going on here? I see this across trees. Did we land something recently that broke this?

I don't have insight into the cause of the crashes. I don't see them happening recently -- I think the cause of the crashes has been resolved now.

However, I am concerned about the lack of crash report and particularly the "No symbols path" message.

https://treeherder.mozilla.org/#/jobs?repo=try&revision=d40f567efbf0 introduces an intentional crash. Note that mochitest and reftest crashes are reported correctly with a crash report -- but not on robocop, where the "No symbols path" error is seen consistently.

Comment 4

[Geoff Brown [:gbrown]]

I think I broke robocop crash reporting when I introduced runrobocop.py.

Comment 5

[Geoff Brown [:gbrown]]

Attachment: pass symbolsPath to automation.runApp

options.symbolsPath was not being passed to automation's runApp() (which eventually calls down to mozcrash), from runrobocop.py only. This passes the symbols path correctly.

Fix demonstrated at https://treeherder.mozilla.org/#/jobs?repo=try&revision=40c42ce8891c:
