Werner Lemberg 093c182058 [truetype] Avoid reexecution of `fpgm' and` prep' in case of error. Reported as https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=981 * include/freetype/fterrdef.h (FT_Err_DEF_In_Glyf_Bytecode): New error code. * src/truetype/ttinterp.c (Ins_FDEF, Ins_IDEF): Prohibit execution of these two opcodes in `glyf' bytecode. (TT_RunIns): Don't enforce reexecution of `fpgm' and `prep' bytecode in case of error since function tables can no longer be modified (due to the changes in `Ins_FDEF' and `Ins_IDEF'). This change can enormously speed up handling of broken fonts.	2017-04-03 11:37:33 +02:00
