Comment 1 Dominik Röttsches (drott) 2013-01-30 02:06:51 PST 
My assumption is, this happened after bug 106142, r140999.
Comment 2 Jussi Kukkonen (jku) 2013-01-30 10:14:41 PST 
This is asserting as well:
compositing/overflow/clip-content-under-overflow-controls.html
Comment 3 Simon Fraser (smfr) 2013-01-30 14:44:02 PST 
This is related to compositing scrolling. Mac shows it also.
Comment 4 Ádám Kallai 2013-01-31 06:04:16 PST 
These tests assertion fail on Qt debug too.

Comment 6 Jessie Berlin 2013-01-31 11:31:27 PST 
I am going to mark these as Crashing in Debug in platform/mac’s TestExpectations, since nobody appears to be actively working on this.
Comment 7 Jessie Berlin 2013-01-31 12:02:28 PST 
Marked the tests as crashing in debug for mac in http://trac.webkit.org/changeset/141457
