Jacob's revision has a typo. The first time this happened was r257127, so this is almost certainly http://trac.webkit.org/r257126. Also, this is happening 100% on the GuardMalloc bot.

Ok. It looks like some timing issue. Most likely it's missing some forced layout (since the test seemed to rely on an optional layout).
