Comment 1 Lauro Moura 2020-07-09 22:20:36 PDT 
In build 14583 (r264207), compositing/video/video-clip-change-src.html crashed with the same backtrace.

First crash in almost 20k revisions. I'll keep it as failure only for now. If they become frequent, we can mark it as crash too.
Comment 2 Diego Pino 2020-07-28 03:33:09 PDT 
Also compositing/video/video-reflection.html in https://build.webkit.org/builders/GTK%20Linux%2064-bit%20Release%20%28Tests%29/builds/14915. Same crash backtrace.
Comment 3 Diego Pino 2021-06-04 19:37:02 PDT 
This test, or group of tests, has been passing for the last 4000 revisions. Closing bug. Gardened in r278519.
