Attached file testcase
This terrible testcase, which has visible <style> elements, triggers:

###!!! ASSERTION: continuations should have the same style context: 'oldContext == nextContinuationContext || oldContext->GetPseudo() != nextContinuationContext->GetPseudo() || oldContext->GetParent() != nextContinuationContext->GetParent()', file /Users/jruderman/mozilla-central/layout/base/nsFrameManager.cpp, line 1303
Oops, I forgot to mention that it only triggers the assertion half of the time.
The two contexts in question are the style contexts for the <style style="position: absolute; display: block;">, which are two block frames (continuations of each other), both children of block frames for the :-moz-column-content of the HTML element (i.e., columns).  aFrame is on the absolute list of the first column; its next continuation is on the overflow containers list of the second column.
