That can be tracked down rather easily now that we have GIT rather than
CVS driving our repository, but I'm more concerned they might be symptoms
of unfinished or buggy code. This is hairy stuff (by definition, actually
-- where there's no DWARF information available we should try PDR records
first, where available, before resorting, in desperation, to heuristics).
