This is a test case that I added recently, I will investigate later today.
The test case was added in Bug 1330373.

What should I do to reproduce a CCov build locally?

Attachment: Skip xdr/relazify.js test case.

This test case got added in Bug 1330373 and check if decoded function can
successfully be relazified.  Which goes against the code coverage approach
of preventing the relazification in order to keep the counters alive.

I do not see how these could happen now that the test case is in the filtered list.

Based on the orangefactor graph, it stopped on the 20th of June and nothing else has happened since then. It looks lile it is disabled now though. So, we have nothing to worry about here (unless we get a failure within the next week). :)
