Aha!
(gdb) show height
Number of lines gdb thinks are in a page is unlimited.
(gdb) show environment INSIDE_EMACS
INSIDE_EMACS = 28.0.50,comint
It is indeed unlimited... but if I change the size of the frame:
(gdb) show height
Number of lines gdb thinks are in a page is 35.
So Emacs is somehow telling gdb to set the height when the frame size
changes. I tried grepping for that yesterday, but I was unable to see
what triggers that.
