We see some occasional crash happening in Frame::transferChildFrameToNewDocument when we try to transfer the frame and close the document at the same time.

Comment on attachment 73148 [details] Proposed Patch I guess there is no way to test it from layout test... We don't even have a repro case for it, only crash stack. Anyways, the check looks reasonable. r=me

Why can't you test it? A +-B +-C +-D In A, grab B's document and then detach frame B from the DOM. Now, grab C and try to adopt it as a child of D.
