Hi Cheng!
Ah, it was the information that the expressions should be placed in the init file that I was missing.
I can confirm that I can reproduce the problem using the following recipe.
Place the following lines in a file, say bug22298.el:
(when window-system
(set-frame-size (selected-frame) 155 38 nil)
(tool-bar-mode 1))
emacs -Q -l bug22298.el
Here, Emacs use its standard frame size whereas it should use the newly specified size (155x38).
