Hm, the possible cause is that you have the ~/.emacs-w3m.elc file
or that you've changed the value of the `w3m-init-file' variable
to something other than "~/.emacs-w3m".  Though both are unlikely.

The default value of `w3m-init-file' is "~/.emacs-w3m" and it is
loaded when loading w3m.elc.  But .emacs-w3m.elc or .emacs-w3m.el
is preferred (in this order) if it or both exist in addition to

cf. (info "(emacs-w3m)Minimal Settings")
    (info "(emacs-w3m)Customizable variables")

If Emacs on Mac doesn't load the .el file, though I don't believe
it, it might be worth trying changing of the file name into
"~/.emacs-w3m".  The last resort is to put the following in your
~/.emacs file:

(eval-after-load "w3m"
  '(add-to-list 'w3m-command-environment '("GC_NPROCS" . "1")))


(eval-after-load "w3m"
  '(load "~/.emacs-w3m.el"))

P.S. Thanks Dai Sato for following up[1] to this thread.  For
non-Japanese subscribers, he wrote that the cause of the problem
seems to be due to Boehm GC 7.0.  He also presented an example
that it is solved by downgrading the version of GC to 6.8. --[2]
