Here you go:

(gdb) frame 23
#23 0x00005555556d097f in xg_frame_set_char_size 
(f=f <at> entry=0x55555630eb60, width=width <at> entry=1728, 
height=height <at> entry=1620) at gtkutil.c:1425
1425	      x_wait_for_event (f, ConfigureNotify);
(gdb) print f->column_width
$2 = 21
(gdb) print f->line_height
$3 = 45
(gdb) frame 26
#26 0x000055555568f0e6 in x_new_font (f=0x55555630eb60, 
font_object=XIL(0x5555560e3465), fontset=27) at xterm.c:26576
26576	      adjust_frame_size
(gdb) print font->average_width
$4 = 21
(gdb) print font_ascent
$5 = 37
(gdb) print font_descent
