fix crash in glyph-cachels -------------------- ChangeLog entries follow: -------------------- src/ChangeLog addition: 2010-02-03 Ben Wing <ben@xemacs.org> * frame.c (Fmake_frame): * glyphs.c: * glyphs.c (NUM_PRECACHED_GLYPHS): * glyphs.c (get_glyph_cachel_index): * glyphs.c (FROB): * glyphs.c (mark_glyph_cachels_as_not_updated): * redisplay.c (regenerate_window): * redisplay.c (redisplay_window): When creating a frame, call reset_glyph_cachels on the minibuffer window as well as the root window. Fixes a crash due to other glyphs (e.g. the gutter glyph) getting in the glyph cachel before the pre-cached glyphs that are supposed to have fixed indices (continuation-glyph, truncation-glyph, etc.). Add a bunch of asserts to make sure that the glyph cachels always properly contain the pre-cached glyphs.
