Noticed this problem on the following UA: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.36

Able to reproduce the issue on Linux Ubuntu-14.04 using chrome stable version 58.0.3029.110 and reported version 60.0.3095.5 with the steps mentioned in comment#0.
This is Non-regression issue, observed from older versions of chrome M48 #48.0.2540.0 and marking this as Untriaged to get more inputs from dev team.

Note:Issue is specific to Linux.
Thanks.

Will take a look. Thanks for the report, as always.

Looks like this is what happens when we block through the DCHECK in a release build.
