[ft-devel] Freetype render issue

[Johnson Y. Yan]

Hi,

 

http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=ebda8b32573726cd6da483b4018913dc2d3f2bb4

 

/* the `eexec' keyword); if they all are hexadecimal digits, then */

/* we have a case of ASCII storage */

- if ( ft_isxdigit( cur[0] ) && ft_isxdigit( cur[1] ) &&

+ if ( cur + 3 < limit &&

+ ft_isxdigit( cur[0] ) && ft_isxdigit( cur[1] ) &&

ft_isxdigit( cur[2] ) && ft_isxdigit( cur[3] ) )

{

/* ASCII hexadecimal encoding */

 

 

The code seems to make some side effects, attachment is the test file, it renders error.

May be need to reset the limit pointer:

t1parser.c: line 395:

 

    Found:

      parser->root.limit = parser->base_dict + parser->base_len;

      T1_Skip_PS_Token( parser );

      cur = parser->root.cursor;

      limit = parser->root.limit;

....

 

Please help to check.

 

Thanks.
