See attachment for full log.
I think this is happening because the thread is still active when shutdown happens?
I haven't seen any such crashes on live runs. I'll pref it off for marionette for now, and see if any crashes happen on nightly.

I believe I've seen this in the wild on Linux 64-bit.

These have already been addressed in bug 1881437.
This bug is OSX only.

It could also be the case that this happens when called early during startup.
For example, this thunderbird crash: https://crash-stats.mozilla.org/report/index/7617f59f-b983-425a-a96d-3b2600240228 happens 5 seconds after startup. Though there is one happening 75 seconds after startup.

It seems that this might be a common OSX issues, which is why the feature is currently preffed off for OSX.
We probably need to file a bug with Apple.

Hi Valentin, do you have plans to investigate this crash? I would be interested to see this feature enabled as well for Marionette tests so that we are closer to what we ship to our users. Thanks.

I submitted FB13820017 to Apple regarding res_query, along with a reduced test case for the API not working well in multiple threads.
See attached file.

I don't think there's much we can do to fix this issue in Gecko.
For now the feature is disabled both for webdriver and users.

I see. Thanks for letting us know!

Closing because no crashes reported for 12 weeks.
