Your experience and mine are identic but the problem goes as follows:
The OP observed that the height of the initial (first) frame differs
from that of additional frames.  We found out that their heights differ
by the height of the toolbar, that is, additional frames are by the
height of the toolbar higher than the initial (first) frame.  So if you
say that the initial frame is good, the bug must be with the additional
frames and _not_ with the initial one.  Hence we've been discussing the
problem with different premises.

As Jan said this code is executed exclusively with the native toolbar,
hence we would have to judge whether not executing that code DTRT for
toolkit scrollbars.  With the native toolbar, this code is not executed
for the initial frame (at least not here), hence we would have to judge
whether not executing that code for the initial frame does TRT.  Here,
this code gets executed only for additional frames and iff I have
toolbars enabled.

Please recall that I didn't use -g to produce the bug, just a
single-line .emacs containing

(add-to-list 'default-frame-alist '(height . 37))

What I wanted to express above is that my initial Emacs frame has the
same height regardless of whether I have toolbars enabled or not.  Also,
the heights of my frames never change when I switch toolbars on and off.
