Done - log attached.
As mentioned in the file, gdb does not seem able to catch all uses of that
function; there's a couple visible frame size changes that don't trigger the
breakpoint.

As an aside, how easy would it be to defer the actual visible frame size
changes until emacs is ready to accept input? That would avoid the "resizing
dance" emacs now does at startup (almost enough to warrant an epilepsy
warning :D).
