While temporarily enabling debug jittests on Android hardware, I ran into this. It requires the additional patch to enable debug. It is reproducible in that it occurred in a retrigger. So far, I have only seen it on pixel2 arm64 debug.

Bob says these Jit7 test failures are perma-fail in ARM64 debug builds:

Adding the [arm64:m3] whiteboard tag because we should fix reproducible test crashes before letting ARM64 Fennec Nightly ride the trains to Beta.

[Jon Coppeard (:jonco)]

Steve, can you take a look at this?

(I had a quick look at the test and couldn't see anything. We disable gczeal at the start and gcslice() looks like it runs with unlimited slice if no argument is supplied).

[Steve Fink [:sfink] [:s:]]

I guess this was already happening. Fortunately, pbone just fixed this.
