This failure also seems the same:
v8.infinite_scroll-classic_tbmv2 failing on chromium.perf/Android Nexus6 Perf (2)

Regression range is the same.

I'm not sure the android and linux issues are the same. On android it just looks flaky. On linux, it is failing every time. The failure also seems to manifest slightly differently. On android it is a crash. On linux memory dumps are timing out:

This is also failing on nexus 5x webview bot, I'll start a bisect there.

Most of these bugs re v8.infinite_scroll_tbmv2 should be handled through  Issue 724262  .

The benchmark is removed.
