Not an intermittent failure, but adding keyword so this shows on TBPL.

Have also hidden ASan m-3 temporarily until this is resolved.

Scratch that, leaving it visible for now, we can just star it

Comment 3

[Andrew McCreight [:mccr8]]

The nice thing about the LSan failure we've had is that you can still see when it has failed by checking the short log.  We had a failure like this before, but it was fixed, so this is a very recent regression.  It looks like it happened in the last merge to central:
  https://tbpl.mozilla.org/?rev=08c23f12a43e

If jesup can't figure something out in the next hour or so, I can land an LSan suppression for this, in the interest of sherriff harmony, but obviously it is not great to hide all GMP process leaks or whatever this is.

Comment 4

[Andrew McCreight [:mccr8]]

It looks like this is a regression from bug 1012951.

This push has the leak:
  https://tbpl.mozilla.org/?tree=Mozilla-Inbound&rev=d50d7e88f35e

The previous push does not have this leak in its M3 ASan log:

Ah great :-)

Backed out bug 1012951.

Yep, the backout fixed this.

> Yep, the backout fixed this.

So, if I'm reading the log correctly, it's a leak in the parent process, which my patch didn't directly affect.  My guess is that the child process died from a sandbox violation caused by the LSan instrumentation, the log messages for that would have gone to /dev/null because NSPR, the crash dump wouldn't happen because LSan apparently requires disabling the crash reporter, and the parent process code has an existing error-case leak that the normal tests don't cover.

sched_getaffinity.  Which doesn't look like it should be LSan-specific, so I'm thinking it's not — it's part of some event that's not ordered with respect to sandbox start, so what it really is is timing-dependent.
