I had to recreate the error, so to make sure the numbers were
consistent, I re-printed out these positions from different frames:
Breakpoint 1, abort () at emacs.c:390
(gdb) up
#1 0x080779e7 in init_iterator (it=0xbfffa878, w=0x88e30d0, charpos=308,
bytepos=311, row=0x0, base_face_id=DEFAULT_FACE_ID) at xdisp.c:2507
(gdb) up
#2 0x080794bb in init_from_display_pos (it=0xbfffa878, w=0x88e30d0,
pos=0x8d60df0) at xdisp.c:2951
(gdb) p *pos
$9 = {
pos = {
charpos = 308,
bytepos = 311
},
overlay_string_index = -1,
string_pos = {
charpos = -1,
bytepos = -1
},
dpvec_index = -1
}
(gdb) up
#3 0x08079810 in init_to_row_end (it=0xbfffa878, w=0x88e30d0, row=0x8d60d88)
at xdisp.c:3054
(gdb) p row->end
$10 = {
pos = {
charpos = 308,
bytepos = 311
},
overlay_string_index = -1,
string_pos = {
charpos = -1,
bytepos = -1
},
dpvec_index = -1
}
(gdb) up
#4 0x080a82f0 in try_window_id (w=0x88e30d0) at xdisp.c:17140
(gdb) p row->end
$11 = {
pos = {
charpos = 309,
bytepos = 313
},
overlay_string_index = -1,
string_pos = {
charpos = -1,
bytepos = -1
},
dpvec_index = -1
}
(gdb)
