Created attachment 530821 [details] testcase ###!!! ASSERTION: aPrevFrame must be the last continuation in its chain!: '!aPrevFrame || (!aPrevFrame->GetNextContinuation() || IS_TRUE_OVERFLOW_CONTAINER(aPrevFrame->GetNextContinuation())) && !IS_TRUE_OVERFLOW_CONTAINER(aPrevFrame)', file layout/base/nsFrameManager.cpp, line 499 Might be a regression from today's cedar merge: http://hg.mozilla.org/mozilla-central/pushloghtml?changeset=62941612320d

I got several reports from the fuzzer soon after the merge, which makes me think it's not a long-standing bug.
