This assertion also happens on following tests: svg/dynamic-updates/SVGFEMorphologyElement-dom-in-attr.html svg/dynamic-updates/SVGFEMorphologyElement-dom-radius-attr.html transitions/interrupt-transform-transition.html And they appear to affect random tests. We need to fix this crash ASAP. It's making all debug bots always red.

Updated the test expectation in
http://trac.webkit.org/changeset/138718
but this is really a losing battle as the assertion failure appears to affect random tests.

It’s hard to tell because this is an intermittent failure.

Also has a crash in SharedBuffer::hasPlatformData(). Despite of the fact I only comment on this bug few times a day, this crash is recurring on bots extremely often and preventing us from making WebKit2 bots green.

Any update on this? We are still seeing this intermittently (e.g:

This is the most common remaining cause of red bots. It affects lots of different tests so we can't just skip tests to avoid it.
