Created attachment 318961 [details] Archive of layout-test-results from ews117 for mac-elcapitan The attached test failures were seen while running run-webkit-tests on the mac-debug-ews. Bot: ews117 Port: mac-elcapitan Platform: Mac OS X 10.11.6
Hm, looks like the first version of the new LayoutTest hits a debug assertion. This happens without my fix as well, and looks like a separate issue than the bug I'm addressing here. Filed https://bugs.webkit.org/show_bug.cgi?id=175923 to track it.
