Oops, thanks for the correction. Since Manuel Giraud found a fix, I
guess it's not worth pursuing this further, but for the record, here are
the outputs I got for the initial display and then after each `C-x C-+'
(up to +5) in the *Customize Face: bold* buffer in Emacs, both without
and with Manuel's fix:
(gdb) p it->ascent
$1 = 13
(gdb) p it->descent
$2 = 3
(gdb) p it->ascent
$3 = 14
(gdb) p it->descent
$4 = 2
(gdb) p it->ascent
$5 = 15
(gdb) p it->descent
$6 = 1
(gdb) p it->ascent
$7 = 16
(gdb) p it->descent
$8 = 0
(gdb) p it->ascent
$9 = 18
(gdb) p it->descent
$10 = -2
(gdb) p it->ascent
$11 = 19
(gdb) p it->descent
$12 = -3
The ascent values are the same as what was displayed in the *locals of
emacs* buffer for glyph_ascent. A difference between the outputs
without and with Manuel's fix is in the values for struct glyph_slice:
without the fix, width and height switched back and forth between 15 and
16, as I noted previously, while with the fix, these values continually
increased with each `C-x C-+'.
