+dtu I see a lot of bisects failing like the one in #6--build fails. Anything we can do?

Comment 8 by sullivan@google.com, May 25 2018 

dtu: ping? Is it possible to patch in a CL now to fix the build definition?

Comment 9 by dtu@chromium.org, May 25 2018 

Yes, it should be possible. Let me kick off a job with https://chromium-review.googlesource.com/992815 patched in.

Comment 12 by dtu@chromium.org, May 31 2018 

An unexpected result. The regression didn't reproduce. All the values were closer to the "after" values.

Looks like this doesn't repro in bisect.
