About a week ago, display-related assertions have been disabled by
default (after being enabled for a month or so).  There have been
tests in there that check that cursor movement makes positive
progress.  So it sounds very much like "the only odd thing" would have
been exactly what made Emacs crash when the assertions were enabled.

I have been one person asking to disable the assertions, since this
kind of bug is easier to analyze if Emacs just behaves strange instead
of crashing.  It is known that the problem is in the "reseat*"
routines which don't necessarily make progress when in images.  This
will probably be fixed at a later time.
