While working on a large patch, I started to see fast/dom/gc-8.html fail with some regularity. Talking with a few other members of the WebKit team I've learn that others have seen it anywhere from occasionally to regularly, as well. I'm attaching the stack trace but I can't capture this in the debugger - the test by itself seems to not fail, and adding tests before it to cause its failure is more of an art than a science.
Created attachment 11813 [details] Crash log for the layout test gc-8.html fast/dom/gc-8.html crash log, here you go! To repro this, I simply ran run-webkit-tests fast/dom - it crashes about 2/3 the way through the top level directory
I've been seeing the same crash.
Did anyone see this before I landed the ICU abstraction? I'm suspicious of that change now even though the crash log looks unrelated.
While the first time I ever saw this problem was today, I haven't updated since Thursday, so the ICU abstraction is out for my tree...
lemme amend and clarify my statement - I'm running on 18092 + local mods. Hyatt landed the ICU abstraction in 18098.
