+	* src/truetype/ttgload.c (load_truetype_glyph)
+	[TT_CONFIG_OPTION_BYTECODE_INTERPRETER]: Call
+	FT_GlyphLoader_CheckPoints before adding phantom points.  This fixes
+	a segfault bug with fonts (e.g. htst3.ttf) which have nested
+	subglyphs more than one level deep.  Reported by Anthony Fok.
+
+	* include/freetype/config/ftoption.h: Define
+	TT_CONFIG_OPTION_BYTECODE_INTERPRETER,
+	TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING, and
+	TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING to make it the new
+	default.
