This is a crash which happens a lot with all kinds of Marionette tests.

I don't think that's quite right. The crash stack appears to be crashing _within_ PR_GetCurrentThread. In particular, the assertion that's firing seems to be here:
http://searchfox.org/mozilla-central/rev/9ec085584d7491ddbaf6574d3732c08511709172/nsprpub/pr/src/pthreads/ptthread.c#292
Which gets called from here:
http://searchfox.org/mozilla-central/rev/9ec085584d7491ddbaf6574d3732c08511709172/nsprpub/pr/src/pthreads/ptthread.c#656
That seems to suggest that the NSPR thread data is missing from the slot, which might indicate that this is running after shutdown or something? I can't really tell because the main thread isn't symbolicated.

The gecko.log actually has an assertion shown which mentions something about shutdown:

Then we hit another regression and abort:
Assertion failure: 0 == rv, at /home/worker/workspace/build/src/nsprpub/pr/src/pthreads/ptthread.c:292
Redirecting call to abort() to mozalloc_abort
Hit MOZ_CRASH() at /home/worker/workspace/build/src/memory/mozalloc/mozalloc_abort.cpp:33
The "0 == rv" assertion looks to be the same as what we have for bug 1252222.
Maybe the above information helps? So far the crash volume is very low (maybe even happened only once) so Orange Factor doesn't track it yet.

Crashstats lists three crashes so far for users (in case those are related):

It looks like maybe a test (or something in the Marionette harness?) could be causing us to leak and then run JS later too late into shutdown. Outside of that, it'll be hard to debug this with only the information we have at hand.

Bobby, we are getting this crash way more often now. Please see all the related see also links to other bugs. Given that it is not crashing permanently it's hard to find a regression window. Would there be a chance for someone to have a look at it?

I personally don't have cycles to investigate this either now or in the new future.
I also don't think we have any particular reason to believe this is XPConnect-related (though I could be wrong). To make progress here we need a platform hacker with time to investigate.

Bobby, do you have a recommendation who might know about that or at least could help with finding another person?

I actually found a crash for a debug build which might be helpful:

Checking the appropriate gecko.log I can see an assertion which finally is followed by the crash:

The assertion is interestingly the same as what we have seen on bug 1252222 and others.
Maybe that helps a bit?

That certainly lends credence to comment 6.

People on njn's team, overholt's team, or various other low-level gecko hackers (like mccr8) would fit the bill. Given that it doesn't fall into anyone's particular domain, I would recommend getting manager buy-in from someone (like njn or overholt) about investigating it, and let them help you resource it.
Finding a consistent way to reproduce the bug would help a lot.

I checked the OrangeFactor links for all dependent bugs and it looks like this is an e10s only issue, which seems to go back to Firefox 51.0a1.

Nicholas or Andrew, is there anything we can do for this particular crasher? It randomly affects us kinda often for Marionette related test suites. Maybe you can give some hints or proposals in what else we could enable to give more details output.

Sorry for the delay. I've thought about this and asked around and my guesses are needinfo'd.

Could this be happening after a thread has already called exit() and started to run destructors, so that PR_GetCurrentThread is racing _PR_Fini and the pthread specific key is already destroyed?

That sounds like as plausible a theory as anything. I have bug 1282862 open in another tab, which has a similarly inscrutable crash that seems to be happening at shutdown, which might have the same root cause.

I just got an instance of this on a Try run, and the this time the crash report actually shows a thread in the middle of exit() running destructors: https://treeherder.mozilla.org/logviewer.html#?job_id=30866804&repo=try#L4090

All the reported test failures as marked as dependent on this bug, have gone away. There is no more crash in the past couple of months. So this issue should have been fixed by some other already landed patch. Closing as WFM.
