Per Jim's comment in https://phabricator.services.mozilla.com/D10299#252254,

I do saw "MOZ_Assert: Assertion failure: IsSafeToRun(), at /builds/worker/workspace/build/src/obj-firefox/dist/include/mozilla/SchedulerGroup.h:78" in logcat-emulator-5554.log

 (This log is from "Job Details" panel on the treeherder https://treeherder.mozilla.org/#/jobs?repo=try&revision=b17d2039c91dbcf78d2b1c3350c2bcef578f96ad&selectedJob=209006333)

I've followed https://developer.mozilla.org/en-US/docs/Mozilla/Geckoview-Junit_Tests to reproduce it locally, and tried to do the following.

1. adb install -r obj-fennec/gradle/build/mobile/android/geckoview/outputs/apk/androidTest/officialWithGeckoBinaries/debug/geckoview-official-withGeckoBinaries-debug-androidTest.apk
Success
2. ./mach geckoview-junit org.mozilla.geckoview.test.NavigationDelegateTest

But I had no luck to produce the crash on my Mac with the Android emulator.
