We are routinely noticing that key gcno files are missing from the linux64 --enable-fuzzing --enable-coverage builds. This appears to be happening intermittently. The most recent instance of this occurred between 5/22 (574a43c224bd) and 5/23 (9a3c2b7dfe84).
The following is a diff of x86_64-unknown-linux-gnu between those two builds.

Marco, can you look into this or find someone to work with Jason and Jesse? This is causing issues in our fuzzing coverage reports, in particular the /servo directory is missing from some coverage reports, causing major fluctuations in our final report.

Me and Calixte talked about this. The intermittency of it is weird, and we came to the conclusion that it might be something related to caches or similar.
We then thought a likely culprit could be sccache, and by searching on Bugzilla I found bug 1334402 and remembered that we then re-enabled sccache for ccov builds in bug 1334940 after making sccache cache gcno files too.
The patch which added support for gcno caching in sccache (https://github.com/mozilla/sccache/pull/260) only added it to C/C++ compilers though, as at the time Rust coverage didn't exist yet.
So, at this point I'm confident that this might actually be it, and that we just need to add support for gcno caching to sccache for Rust compilation. I guess we need to something similar to https://github.com/mozilla/sccache/pull/260/files in https://github.com/mozilla/sccache/blob/master/src/compiler/rust.rs.
Glandium, is this something you could help with?

Note: probably the underlying cause of bug 1712327 is the same as this one.

There's a PR to fix https://github.com/mozilla/sccache/issues/1021, https://github.com/mozilla/sccache/pull/1052, but Glandium won't be able to review it shortly.
Let's try just disabling sccache for now.
