Issue on type42 parsing in Freetype

    I met an issue in function t42_parse_sfnts, the statement in line 692 seem incorrect as below:

size = (FT_ULong)( limit - parser->root.cursor );

   this parser->root.cursor is changed, result the size takes incorrect value, it is not size of sfnt table. 

   I use the freetype 2.11.0 library, the function locates in src/type42/t42parse.c

   Could you give some advice for the issue? Thanks 

  Best Regards
