A large number of unexpected webkit_layout_tests failures on WebKit Mac10.11 (dbg) and Linux Trusty (dbg)

Issue description

1204 unexpected webkit_layout_tests failures on WebKit Mac10.11 (dbg)

+CC dsinclair@chromium.org for Roll src/third_party/pdfium/
+CC jmadill@chromium.org for Roll src/third_party/angle/

I don't see any other rolls on build 14797.
Please help investigate/triage.
 
Can you use links that don't require a machine cert to visit? Just wanted to see if I could see what was in the roll.

Yes, sorry about that... Sheriff-o-Matic isn't making my rotation as easy as it should, the Mac bot links are here:

Linux also started failing widely with build 11673:
https://ci.chromium.org/buildbot/chromium.webkit/WebKit%20Linux%20Trusty%20%28dbg%29/11674 * Failed: 2001 (1 expected, >>>2000 unexpected<<<)

https://ci.chromium.org/buildbot/chromium.webkit/WebKit%20Linux%20Trusty%20%28dbg%29/11672 * Failed: 2044 (2044 expected, 0 unexpected)
The only roll on that build was for Angle, and I just reverted that for an (unrelated?) compile failure in crrev.com/c/1015191

Summary: A large number of unexpected webkit_layout_tests failures on WebKit Mac10.11 (dbg) and Linux Trusty (dbg) (was: 1204 unexpected webkit_layout_tests failures on WebKit Mac10.11 (dbg))
Owner: jmad...@chromium.org
Status: Assigned (was: Untriaged)
Can confirm the ANGLE roll was bad. Sorry about that - a test failure that passed all the CQ tests because it only failed in debug.
The roll was reverted and the auto-roller paused - fix is in the ANGLE CQ.
Status: Fixed (was: Assigned)
problems are fixed. let me close this now.
