Functions changes summary: 0 Removed, 110 Changed, 0 Added functions
Variables changes summary: 0 Removed, 0 Changed, 0 Added variable

110 functions with some indirect sub-type change:

  [C]'function void hb_buffer_add(hb_buffer_t*, hb_codepoint_t, unsigned int)'
has some indirect sub-type changes:
    parameter 1 of type 'hb_buffer_t*' has sub-type changes:
      in pointed to type 'typedef hb_buffer_t':
        underlying type 'struct hb_buffer_t' changed:
          1 data member change:
           type of 'hb_segment_properties_t hb_buffer_t::props' changed:
             underlying type 'struct hb_segment_properties_t' changed:
               1 data member change:
                type of 'hb_script_t hb_segment_properties_t::script' changed:
                  1 enumerator change:
                    'hb_script_t::_HB_SCRIPT_MAX_VALUE' from value '4294967295'
to '-1'




  [C]'function void hb_buffer_add_codepoints(hb_buffer_t*, const
hb_codepoint_t*, int, unsigned int, int)' has some indir
ect sub-type changes:
    parameter 1 of type 'hb_buffer_t*' has sub-type changes:
      in pointed to type 'typedef hb_buffer_t':
        underlying type 'struct hb_buffer_t' changed, as reported earlier

This one appears to be different the the other symmetry errors in that it
appears that you are comparing a 32b version of -1 with a 64b version and that
creates a huge number of ABI symmetry errors.
