Details |
During initial tests with ThreadSanitizer (LLVM version), we get a data race reported as described in the attached log. Trace was created on mozilla-central with changeset 122820:c233837cce08.
According to the TSan devs, most of the reported traces should be real data races, even though they can be "benign". We need to determine if the race can/should be fixed, or put on the ignore list. Even for benign races, TSan devs suggest to fix them (second priority), as they can also cause problems [1].
