Core file will not be generated. Does it occur on multiple sites: No Is it a problem with a plugin? Yes flash Did this work before? Yes chromium-60.0.3112.113-1-x86_64.pkg.tar.xz in archlinux package repo. Does this work in other browsers? Yes Chrome version: 61.0.3163.91 Channel: stable OS Version: archlinux Flash Version: Shockwave Flash 27.0 r0 I can visit other flash sites which use flash to play video. And the home page of douyu.com can show the live video as well. But just the specific live room is crashed. When I downgrade the chromium to version 60(without any other change), the problem is disappeared.

Able to reproduce the issue on version 61.0.3163.91 using Ubuntu 14.04 and on latest canary 63.0.3218.0 with steps mentioned in Comment#0 As its a Regression issue broken in M-61, please find Manual Bisect info as follows: =============== Good Build:61.0.3142.0 (482491) Bad Build:61.0.3143.0 (482834) Crash report ID of Linux: 070b8e442a3e0fa2 Note: Issue is not reproducible on Win 10 and Mac 10.12.1 on version 63.0.3218.0 As tool bisect is invoking all the good build and as per revision bisect set up is not available on Linux, hence updating manual bisect info

Drott, do you have any idea why this change: https://chromium-review.googlesource.com/c/chromium/src/+/544690 ends up triggering the GetFallbackFontForCharacter on the wrong thread? I feel like removing the check, but I don't want to do so without understanding it a bit.
