CrashTracer: 301 crashes in Safari at com.apple.WebCore: WebCore::AccessibilityRenderObject::visiblePositionForPoint const + 297
https://bugs.webkit.org/show_bug.cgi?id=57405
The offending line in this crash was a null pointer access in
m_renderer->document()->topDocument()->renderer()->view()->frameView();
It seems likely that one of those calls was invalid. I could not reproduce and there was no
information on reproducible steps, hence the absence of a layout test.
