gs bugs, or lilypond bugs

[Michael Welsh Duggan]

The latest CVS builds of LilyPond have been triggering what look like
bugs in gs.  I have used both versions of gs in debian unstable
(gs-gpl and gs-afpl), and both of them end up bugging out, albeit in
different ways.  This really seems like a bug in gs, but as it has
never happened before, I wonder what triggered these bugs.  I have
partial ouput from both instances:
