        <pre>Assertion failure in WebCore::FrameLoader::stopLoading() running fast/events tests.

The crash log blames fast/events/form-iframe-target-before-load-crash.html, but run-webkit-tests results blames fast/events/form-onchange.html.

We likely need to run both tests sequentially to reproduce the assertion failure.
