Actually just looking at the error is seems related to the WebRTC roll. Will see if I can revert that.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/8cc48f8f23f2d0864fe5d72ed5102fd6c475c6fa

commit 8cc48f8f23f2d0864fe5d72ed5102fd6c475c6fa
Author: Jamie Madill <jmadill@chromium.org>
Date: Fri Aug 18 14:45:29 2017

Revert "Roll WebRTC 19324:19403 (73 commits)"

This reverts commit 897b5aa9c138b73be735f16067ec2d6ab45c09f2.

Reason for revert:

Probably related to the fact that these bots are still running msvc? I'm trying to finish untangling this today in  Issue 727437 .

Could be: I have not found anything suspicious in the roll so far.

Maybe https://codereview.webrtc.org/3000693003?

No, actually https://codereview.webrtc.org/3001673002

Thanks ynovikov@!
ehmaldonado@ and kjellander@ PTAL: the only WebRTC roll we managed this week was reverted.

Taking over this as Edward is OOO. 
I'm disabling that warning only when Clang compiler is used (not MSVC) in https://codereview.webrtc.org/3003473002/

I've filed  bug 757293  to investigate our missing coverage on WebRTC trybots so we can catch things like this earlier.

The following revision refers to this bug:
  https://chromium.googlesource.com/external/webrtc.git/+/8b844b16eb8d71313d6b5a06e9469f968fcb0446

commit 8b844b16eb8d71313d6b5a06e9469f968fcb0446
Author: kjellander <kjellander@webrtc.org>
Date: Mon Aug 21 04:37:21 2017

Only disable -Wthread-safety-attributes warning for Clang.

Clang is enabled by default and we currently lack coverage for building on Windows
with MSVC (see  crbug.com/757293 ). This should unblock rolling WebRTC into
Chromium DEPS. We need to improve our trybot coverage for standalone WebRTC
to prevent things like this in the future though ( crbug.com/756840 ).

New roll in progress: https://chromium-review.googlesource.com/c/622789
It is running the win_optional_gpu_tests_rel trybot as well, which seems to match the failing ones in https://cs.chromium.org/chromium/src/tools/mb/mb_config.pyl?rcl=8394bae7034e5eeb9bf5ada381fc3ea39baf323a&l=673

FTR: I got permission denied with my kjellander@google.com account to schedule tryjobs at the chromium.angle tryserver. Is that intentional?

[modify] https://crrev.com/faa2a2c3e81a0f6e2a59fd2b72b10b871ab5f034/DEPS

Roll was reverted after another breakage (see [1] for details).

We somehow seem unable to catch in WebRTC standalone. I posted a comment in https://chromium-review.googlesource.com/c/578628 about fixing it but I don't know why it isn't caught either with our own bots or the Chromium CQ trybots.

[1]: https://findit-for-me.appspot.com/waterfall/culprit?key=ag9zfmZpbmRpdC1mb3ItbWVyRAsSDVdmU3VzcGVjdGVkQ0wiMWNocm9taXVtLzg4OWI1ZTdhZThjNDI1NWU2MDBjNzdiYjdiYjQ5ODBmMTAyNmIzN2UM

It looks like the same problem as https://bugs.chromium.org/p/webrtc/issues/detail?id=8108 which was caught by CQ during the roll last week.

Re #17: can you provide links as reference? If it was "caught" by CQ, how could the CL land?

Regarding this bug, niklase@ landed a roll ~4 hours ago in https://chromium-review.googlesource.com/c/chromium/src/+/624696 that seems to stick, so I'm closing this.
I will investigate the remaining unanswered questions about our test coverage as part of  bug 757293 .

Re #18:

from #16 log for https://luci-milo.appspot.com/buildbot/chromium/Win%20x64/14080:

../../third_party/webrtc/call/rtp_demuxer.cc(149): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data

It's the same warning (but in another place) CQ rejected the build with in https://bugs.chromium.org/p/webrtc/issues/detail?id=8108 I refer to (see big description in there).

I'm not sure what is going on here, maybe a race of clang bit flipping on/off in Chromium and WebRTC.

Might require @chromium.org, not sure, but the chromium.angle tryserver is configured to only try patches that apply to src/third_party/angle.

master.tryserver.chromium.win:win_optional_gpu_tests_rel can be used for the moment to catch this, as can master.tryserver.chromium.win:win_clang (which is now really "win_msvc").
