Originally reported here: https://github.com/mozilla/geckodriver/issues/937

With the attached Marionette testcase we can cause switchToParentFrame to fail:

1505201688795	Marionette	TRACE	20 -> [0,34,"switchToParentFrame",{}]
JavaScript error: chrome://marionette/content/listener.js, line 1576: TypeError: can't access dead object

The failure happens with a very low frequency, so using --run-until-failure with --repeat was useful here.

The failing line is:

>    function switchToParentFrame(msg) {
> ->   curContainer.frame = curContainer.frame.parent;
>      let parentElement = seenEls.add(curContainer.frame);

While running the test I have also seen crashes of Firefox in some cases. Maybe that is somehow related.
