Got duped as https://github.com/crossbeam-rs/crossbeam/issues/589

It looks like we'll need to add an exception:

Second, the Chase-Lev (even as the cicbuf variant) algorithm is inherently data-racy. The steal operation first reads data from the buffer and then checks whether something changed in the meantime. If so, the read data is discarded (using mem::forget) and the steal operation has to be retried. Put differently, a data race might happen, but we never follow up on it so UB doesn't happen.

Oh! Ok I just noticed we're missing the ::deque:: part of the signature in our supression. Not sure if that was recently added or if I literally just never saw it, but that explains why all of these are slipping through the cracks!

Assignee: nobody → a.beingessner

they weren't matching due to the lack of ::deque::, so make the * cover more

Pushed by abeingessner@mozilla.com: https://hg.mozilla.org/integration/autoland/rev/de8fa2040132 fix signatures for crossbeam_deque supressions. r=decoder
