Comment 1

[Andreea Pavel [:apavel]]

Benjamin can you please take a look at this? 
It's failed on your push for bug 1469027 and green before that: https://tinyurl.com/ybtjud23

Could bug 1469027 be the cause for this failure?

Comment 3

[Benjamin Bouvier [:bbouvier] (inactive)]

I really don't see how it could be related to my patches, except for changes on the binary layout or PGO issues. Could it also be caused by the "see also" bug?

Comment 4

[Benjamin Bouvier [:bbouvier] (inactive)]

Here's a question: the logs seem to show that this is run with `mach python-test`:

11:16:05     INFO - Starting 'mach python-test' with -j16

There seems to be an explicit remark in a comment of this particular test saying that there's a spurious failure when run with `mach python-test`:

https://searchfox.org/mozilla-central/source/testing/xpcshell/selftest.py#664-668

Could that be it?

Comment 5

[Andreea Pavel [:apavel]]

Geoff can you please take a look here and see if you can think of something or someone who can work on this? 

There are 34 total failures in the last 7 days, 1 on linux64, windows2012-32 opt,pgo and windows2012-64 opt, asan and pgo.

Comment 6

[Geoff Brown [:gbrown]]

Very speculatively: Since this is spawning a new xpcshell test, with unknown mozinfo, could this be related to the fix for bug 1305743 (being backed out now)? Watching for sudden improvement...

Comment 7

[Geoff Brown [:gbrown]]

Failure frequency is significantly reduced, but there are still a few (it's unclear if bug 1305743 is implicated). I haven't had a chance to investigate and at this failure rate, I probably won't. 

Also, bug 1396845 might help here.

Comment 8

[Andreea Pavel [:apavel]]

Thank you for looking into this Geoff.
