Bug 98001 – [chromium] crash when running accessibility/canvas-fallback-content-2.html

When trying to run the test accessibility/canvas-fallback-content-2.html in content_shell like this:

echo file://$(pwd)/LayoutTests/accessibility/canvas-fallback-content-2.html | out/Debug/content_shell  --no-sandbox --dump-render-tree

I get the following crash:

Reverted r130062 for reason:

Causes a ton of gtest failures on the chromium bots

See http://build.chromium.org/p/chromium.webkit/builders/Win%20%28dbg%29/builds/7893 for the failures.

[Ojan Vafai]

It wasn't clear to me whether this assert was showing places where the code is wrong or whether the assert is wrong. Either way, it would be good to fix the gtest failures first.

sorry for the mess. It's indeed a failure in the tests. I'm fixing this.

Landed again http://trac.webkit.org/changeset/130152
