Yes, emacs -q and instrument `if', lot of things gets very confused
(try C-x C-f or C-h f).  Debugging this is beyond my lisp knowledge,
and I'm also not sure if this is even worth trying to fix if it can't
be done easily. (People that profile stuff will probably understand
why this is bad and simply not do it.)
