compositing/webgl/webgl-nonpremultiplied-blend.html crashes on Mac OS X 10.6, Chromium DEBUG build
Apparently, this started after r83552.

This is reproducible. It seems necessary to reload the page and then wait a second. The following is printed to the console when the renderer crashes:

ASSERTION FAILED: !m_deletionHasBegun
../../JavaScriptCore/wtf/RefCounted.h(37) : void WTF::RefCountedBase::ref()

This is likely caused by the HashMap of RefPtrs to GraphicsContext3D instances.

The crash does not seem to happen in Linux -- I tried lots of reloading, duplicating and closing the tab. Is it trivial for you to post the call stack from Mac?

[Kenneth Russell]

Yes. I'll add it as an attachment since it's large.

I'm also marking media/adopt-node-crash.html as CRASH with a reference to this bug, as it started crashing on GPU tests on Mac SL debug since about the same time:
