CF doesn't do component builds, and I'm testing a change to fix this now.

r287780 should fix the problem, but I'm not sure how much we can rely on the 256 byte padding heuristic.

It now crashes elsewhere:

Let's try r288096.

The builder went green when it got that revision in https://build.chromium.org/p/chromium.fyi/builders/CrWinAsan%28dll%29/builds/5301.

However, the tester is purple because browser_tests isn't running. We probably need to copy the ASan runtime DLL around or something.

Looks like HID.DLL is in the way of the shadow memory mapping. We have an issue that we closed as stale for that ( http://crbug.com/515604 ). Let's close this and reopen that.
