Bug 43939 – WebKit2 crashes when WebFrame outlives WebPage

• Component: WebKit2
• Status: RESOLVED FIXED

[Maciej Stachowiak]

WebKit2 crashes when the WebFrame outlives the WebPage, which can validly happen. For example, this occurs on fast/dom/Document/early-document-access.html

This can be avoided by making sure all the linkage is at the WebCore level.
