I haven't investigated this further and/or how long this is the case, but it seems wrong... e.g. https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=a32e3b93c8d8 https://treeherder.mozilla.org/logviewer.html#?job_id=1355929&repo=mozilla-central SUMMARY: AddressSanitizer: 144 byte(s) leaked in 2 allocation(s). SUMMARY: AddressSanitizer: 576 byte(s) leaked in 8 allocation(s). and https://treeherder.mozilla.org/logviewer.html#?job_id=1357184&repo=mozilla-central SUMMARY: AddressSanitizer: 288 byte(s) leaked in 4 allocation(s). SUMMARY: AddressSanitizer: 432 byte(s) leaked in 6 allocation(s). SUMMARY: AddressSanitizer: 720 byte(s) leaked in 10 allocation(s). Can we either ensure this doesn't show up in logs if it's not harmful, or ensure it turns the machine orange or whatever so it gets investigated and fixed etc. ? :-) I'm not really sure where this goes, so please move as appropriate...

These are whitelisted leaks. AFAIK, there's no way to suppress them.

Can you help with this one, please?

I don't know anything about leaks and ASan. :mccr8 is probably a better person to ask, forwarding.

We used to ignore indirect leaks. That's probably what this was. I don't see any in a current bc1 ASan log.
