compositing/webgl/webgl-nonpremultiplied-blend.html crashes on Mac OS X 10.6, Chromium DEBUG build
Apparently, this started after r83552.
Comment 1 Kenneth Russell 2011-04-12 13:32:35 PDT 
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?

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:
