Hi Nico.

Recent Chrome hits various DoDelete crash as tracked by http://crbug.com/393634
.
But each of the crash reports have slightly different signature for day by day,
which is due to the link time optimization on Windows.
So, it's hard to know identify which class actually causes the crash.

Can I hold the signature string for next a few canaries to identify the culprit?

lgtm. Please remember to remove it again once you have your stack :-)
