[Lauro Moura]

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.

[Diego Pino]

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.

[Diego Pino]

This test, or group of tests, has been passing for the last 4000 revisions. Closing bug. Gardened in r278519.
