Package: pango1.0
Version: 1.20.2
Severity: normal
While running the command doxygen for my project,
which somewhere runs 'dot graph_legend.dot -Tpng:gd -o
graph_legend.png', dot prints:
Pango-WARNING **: Error loading GPOS table 5503
This occurs because in line
pango1.0-1.20.2/pango/opentype/harfbuzz-gpos.c:664,
error is set to HB_Err_Invalid_SubTable_Format:
663 default:
664 return ERR(HB_Err_Invalid_SubTable_Format);
This is a switch for the variable an-PosFormat in line 575:
575 switch ( an-PosFormat )
an-PosFormat has value 56 at that moment, and was read just
before on line 571:
571 an-PosFormat = GET_UShort();
GET_UShort is a macro that depends on stream-cursor
stream is at the point:
(gdb) p *stream
$112 = {base = 0x2b7330d17000 , size = 465256, pos = 454286,
descriptor = {value = 47773740265472, pointer = 0x2b7330d17000},
pathname = {value = 6732768, pointer = 0x66bbe0}, read = 0,
close = 0x2b732ee23b90, memory = 0x62b960, cursor = 0x2b7330d85e8e ,
limit = 0x2b7330d85e8e }
The file associated with this stream is:
(gdb) p *((char(*)[60])stream.pathname.pointer)
