Not 100% sure if this is due to a v8 change or an asan change, but asan feels more likely.

Bot's been red for 4 days now :-/

This is a known issue.
The patch is not yet landed
  https://reviews.llvm.org/D25946

And other fix for a bug with prevent_icf is also on it's way.

Comment 2 by etienneb@chromium.org, Feb 17 2017 

FYI: There are strings allocated within the CRT that are allocated before allocation functions can be hooked. ASAN won't have full coverage on this rare cases.

Comment 3 by thakis@chromium.org, Feb 17 2017 

The bot used to be green. Did someone land upstream that regressed this?

Please always keep upstream trunk green. If something lands upstream that you know broke something, please revert first and fix later.

Comment 4 by etienneb@chromium.org, Feb 17 2017 

This was only failing on 64-bit?
If it's failing on a 32-bits, than the fix may be wrong.

Comment 5 by thakis@chromium.org, Feb 17 2017 

That's a 32-bit bot.

Comment 6 by etienneb@chromium.org, Feb 17 2017 

ok. I'm gonna take a look to it.
Thx to report it.

Comment 7 by thakis@chromium.org, Feb 17 2017 

(But maybe mkpeephole is a 64-bit host binary? Not sure. In any case, that bot used to be happy until 4 days ago.)
