What does the following show?
(gdb) fr 3
(gdb) source /path/to/emacs/src/.gdbinit
(gdb) p it->what
(gdb) p/x it->c
(gdb) pgrowx it->glyph_row
The last command should display the entire glyph row you have there,
which maybe will tell us something useful. The two commands before it
could also be useful.
