But the part that you left in the code also uses it.glyph_row, which
is garbage after a call to move_it_to.  There's a single use of
it.glyph_row->x before the call to PRODUCE_GLYPHS (&it2), and I think
that needs to be fixed as well, because it potentially dereferences a
bad pointer.

Or did I miss something?
