I noticed that the original failure

is the origin of 'counter-suffix-ref.html' test failures.
This failure coincides with the first failure marked in Orange Factor for bug 1460108 and it fails 2 times out of 21 tries.

Hi Emilio -- This looks like a regression from Bug 1445392.  Can you take a look?

Comment 3

[Emilio Cobos Álvarez (:emilio)]

My patch added a crashtest, which probably tweaked the order of the test and moved this intermittent around.

This is a well-known win7-debug intermittent cause (bug 1392106). Joel, looks like your changes didn't fix everything?

:emilio- correct- there is no way to fix the problem 100%, I have reduced the problem and need more data to see what remains.  If this is windows 7 debug only failures, then it will be on my radar.
