That seems to suggest that s->font is invalid, but s->font_not_found_p
is not set. Can you see what characters are being drawn here
(s->first_glyph->u.ch) so you can narrow down which font should be being
used (based on earlier versions) and start stepping through the code
earlier (use a conditional breakpoint based on the character being
displayed).
