I tried that now, and debug-on-entry-ing that function does not result
in that function giving a backtrace...

AAARGH!  It's, once again, the problem of the debugger not being allowed
to be called when inhibit-redisplay is bound, which is seems to be
here.  I wish we could fix that, or at least have `debug' say "Not
entering the debugger because inhibit-redisplay is set"...

Anyway, set-process-window-size is indeed called in M-x gud-gdb
buffers.  So does M-x gdb buffers...  but in that case, gdb just seems
to ignore it, as it should.  So M-x gdb sets up gdb in a way that
gud-gdb doesn't.
