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.
