The error is this clause in apa_bad.erl:

    get_svc_tag(type = eme_lir) -> svc_init.

"type" should have been "Type". The compiler (R9) has apparently already
been extended to ``handle'' such incompatible aliases by quietly making
the clause unselectable, but this should preferably be detected by
erl_lint so that you would get an error message instead.
