Could you document the ASSERTS here, so the author has an easier time fixing?

Thank you, btw.

I added Chromium debug crash expectations in r140108.

Here is the assert; this one from html5lib/run-template.html on Mac 10.7 dbg:

Patch

[Rafael Weinstein]

Note that 140101 wasn't ever rolled out.

This patch fixes the template crash, and removes the TestExpectations for the crashes

Also, note that fast/forms/associated-element-crash.html doesn't correctly name a layout test. I assume this was a meant to be fast/forms/form-associated-element-crash.html, but since it isn't crashing on the bots and I couldn't repro locally, and thus the crash was a flake.
