Comment 1

[Tom S. (please needinfo tschuster)]

I don't see how my change would cause this failure. Andrew any ideas?

Comment 2

[Andrew Sutherland [:asuth] (he/him)]

The log includes lines like:

[task 2020-01-04T11:11:32.184Z] 11:11:32     INFO - GECKO(16120) | console.log: "RemoteSettingsWorker error: ConstraintError: A mutation operation in the transaction failed because a constraint was not satisfied."

which strongly suggests that the build is suffering from bug 1601707 which is a gcc mis-compilation of IndexedDB resulting in correctness failures. Moving to the code coverage component for their knowledge of the toolchains/builds in use.

Comment 4

[Simon Giesecke [:sg] [he/him]]

I landed the patch from Bug 1601707 which ought to fix the miscompilation with gcc, so the dependency on Bug 1499663 can probably be removed again.

Comment 5

[Simon Giesecke [:sg] [he/him]]

I reproduced this locally, and verified that it is fixed by Bug 1601707, so I will close this as a duplicate of that.
