Hi James, Samuel,

I added a temporary expectation for disabling this test, would you mind taking a look and then reverting the expectation?

Thanks!
Marcus

Odd, this test is not failing on my local build. I'll sync to head and try again to see if I can repro. By the way, my first name is Fady, and my last name is Samuel. :)

Thanks for taking a look Fady! :)
I have it consistently failing on my local linux box, ping me if you need more data.

Ok, been able to repro. Looks like I can repro it about once every 10 runs or so. I'm guessing I introduced a subtle bug...maybe touching uninitialized memory in some cases or whatnot causing inconsistent behavior. I'll look into the the issue and get a patch out as soon as I can.

Fady.

tables/mozilla_expected_failures/bugs/bug89315.html also becomes flaky after webkit roll r63992, maybe the same reason?

The patch I posted for bug 42993 addresses this issue as well:
