Sorry, copy & paste error. The regression range is between the two nightly builds.

More likely http://trac.webkit.org/changeset/118416 than http://trac.webkit.org/changeset/118413

http://trac.webkit.org/changeset/118413 doesn't seem like it would affect x86, but I could be wrong.

Ah! This isn't a JSC regression. I can see the same regression on Chromium's latest trunk build.
Comment 8 Ryosuke Niwa 2012-05-24 22:13:38 PDT
This is a DOM or rendering regression.
Comment 9 Ryosuke Niwa 2012-05-24 22:23:31 PDT
Chromium r138925: bad! -> WebKit r118406
Chromium r138884: good! -> WebKit r118384
See http://src.chromium.org/viewvc/chrome/trunk/src/DEPS?view=log
