[Chromium] fast/canvas/webgl/renderbuffer-initialization.html intermittently crash

• Component: WebGL
• Status: RESOLVED DUPLICATE

[Ryosuke Niwa]

On Chromium Windows Debug bots, fast/canvas/webgl/renderbuffer-initialization.html intermittently crash both on deps and canary bots:

Here's the backtrace, which is in url_util underneath KURLGooglePrivate::init. It looks unrelated to WebGL. I don't know why it wouldn't be happening deterministically; a race condition?
