This starts happening somewhere between
rustc 1.47.0-nightly (7e6d6e5f5 2020-08-16)
and
rustc 1.47.0-nightly (792c645ca 2020-08-17)

Severity: -- → S3
Priority: -- → P3

Actually , 84 is unaffected because the part of bug 1644624 that causes these failures hasn't landed.

(In reply to Mike Hommey [:glandium] from comment #2)

This starts happening somewhere between
rustc 1.47.0-nightly (7e6d6e5f5 2020-08-16)
and
rustc 1.47.0-nightly (792c645ca 2020-08-17)

And the specific commit where it stated happening is 33c96b4d9782cf6364e47cb2c904e66b06c22bb4 (merge of https://github.com/rust-lang/rust/pull/74748) but it doesn't seem related, except for the fact that it might make rust code faster.

The failures, per https://treeherder.mozilla.org/#/jobs?repo=try&revision=45f8147af4c936bdc27903eed7a1336898ab7eac seem largely related to scrolling.

This appears to be fixed in more recent nightlies, which require bug 1667736

Ok, everything lines up:

This means we'd need to upgrade to at least nightly-2020-09-19. Let's then go with the latest that was versioned 1.48.0-nightly.

Summary: Linux 18.04 x64 tsan opt mochitest failures as regressed by Bug 1644624 → Upgrade tsan builds to >= nightly-2020-09-19

The first versions with 1.48 had a regression that was fixed later
during the 1.48.0 development phase. Use the last of those to have
something closer to a release, but still versioned 1.48.

Forgot that bug 1667736 needed to land first.
