* src/truetype/ttpload.c (tt_face_get_location): If `pos1', the
offset to the requested entry in `glyf' exceeds the end of the
table, return offset=0, length=0. If `pos2', the offset to the
next entry in `glyf' exceeds the end of the table, truncate
the entry length at the end of `glyf' table.
See Savannah bug #31040.
* src/sfnt/ttpost.c (load_post_names): Get the length of
`post' table and pass the limit of `post' table to
load_format_20() and load_format_25().
(load_format_20): Stop the parsing when we reached at the
limit of `post' table. If more glyph names are required,
they are filled by NULL names. See Savannah bug #31040.
* src/truetype/ttinterp.c (free_buffer_in_size): Don't duplicate
FT_GlyphZoneRec size->twilight to be freed. If duplicated,
FT_FREE() erases the duplicated pointers only and leave original
pointers. They can cause the double-free crash when the burst
errors occur in TrueType interpreter and free_buffer_in_size()
is invoked repeatedly. See Savannah bug #31040 for detail.
Patch is suggested by Adrian Bunk, to prevent unexpected
reflection of environmental LIBTOOL. See:
http://savannah.nongnu.org/patch/?7290
* builds/unix/unix-cc.in: LIBTOOL is unconditionally set to
$(FT_LIBTOOL_DIR)/libtool. FT_LIBTOOL_DIR is set to $(BUILD_DIR)
by default.
* configure: When configured for the building out of source tee,
FT_LIBTOOL_DIR is set to $(OBJ_DIR).
* src/truetype/ttinterp.c (TT_RunIns): Decrease the trace level
showing the error when the interpreter returns with an error,
from FT_TRACE7() to FT_TRACE1().
* src/truetype/ttinterp.c (free_buffer_in_size): New function to
free the buffer allocated during the interpretation of this glyph.
(TT_RunIns): Unset FT_Face->size->{cvt_ready,bytecode_ready} if
an error occurs in the bytecode interpretation. The interpretation
of invalid bytecode may break the function definitions and referring
them in later interpretation is danger. By unsetting these flags,
`fpgm' and `prep' tables are executed again in next interpretation.
Fix Savannah bug #30798, reported by Robert Swiecki.
* src/cff/cffload.c (cff_charset_load): Fix change from 2009-03-20:
The threshold for SIDs is not applicable here. I misinterpreted the
`SID values 65000 and above are available for implementation use'
sentence in the CFF specification.

before TrueType faces, because a Type42 face refers another
