Description Alexey Proskuryakov 2015-01-31 10:07:25 PST

inspector/css/selector-dynamic-specificity.html crashes sometimes, and it actually might have started recently (flakiness dashboard shows crashes on January 29 and today).

It's also slow (probably needs a [ Slow ] expectation), but that's a separate issue.

Comment 2 Alexey Proskuryakov 2015-02-10 16:10:48 PST

Skipped in r179899.

Comment 3 Alexey Proskuryakov 2015-02-16 23:16:03 PST

Happens on WK1 too, so I'll move the Skip expectation from platform/mac-wk2 to platform/mac.

Comment 4 David Kilzer (:ddkilzer) 2015-02-22 12:25:02 PST

Skipped on ios-simulator in r180489.

Previously skipped on win in r179208 with Bug 137157.  Updated to point to this bug in r180489.

Comment 5 Joseph Pecoraro 2015-05-05 13:30:23 PDT

Lets dup this to another bug tracking an identical crash.
