I don't know whether we have an issue in the tracker for this, but it
will always be an issue since there is no valid output for this input
(I don't think one can have both a flag and a stem tremolo).  Aborting
with a core dump (and a cryptic message not obviously related to the
input) is of course about the worst possible diagnostic, but we would
not be able to produce valid graphics either.
