My assumption is, this happened after bug 106142, r140999.

[Jussi Kukkonen (jku)]

This is asserting as well:
compositing/overflow/clip-content-under-overflow-controls.html

[Simon Fraser (smfr)]

This is related to compositing scrolling. Mac shows it also.

[Ádám Kallai]

These tests assertion fail on Qt debug too.

I am going to mark these as Crashing in Debug in platform/mac’s TestExpectations, since nobody appears to be actively working on this.

[Jessie Berlin]

Marked the tests as crashing in debug for mac in http://trac.webkit.org/changeset/141457
