It seems that the failure is due to a native crash in V8 GC:

There were 2 V8 rolls in the revision range:

https://codereview.chromium.org/2083243003 -> https://chromium.googlesource.com/v8/v8/+log/4f1b295d..4e627b31
https://codereview.chromium.org/2086263002 -> https://chromium.googlesource.com/v8/v8/+log/4e627b31..2254a8bd

bmeurer: You had the most changes in the two V8 rolls. Is there any chance any of them could have caused this? If not (and this is not just a flake), I'll kick off a bisect.

If the test is disabled, please downgrade to Pri-2.
