Hi,
A Mac user provided to me a font suitcase file
(OptaneCompactExtrabold.fam) that crashes FreeType (2.3.5 and latest
CVS) when referencing face index #3. I tracked it down to the first call
in FT_New_Face_From_SFNT (ftmac.c).
sfnt = GetResource( FT_MAKE_TAG( 's', 'f', 'n', 't' ), sfnt_id );
if ( ResError() )
return FT_Err_Invalid_Handle;
GetResource would return 0, but ResError did not return true. Checking
for a NULL handle was required to get FreeType to skip it without crashing.
if ( sfnt == NULL || ResError() )
return FT_Err_Invalid_Handle;
I can now access the 7 faces that is reported to be inside with this change.
Hope that is helpful.
Deron
