I do not have a Mac and for this reason perhaps I should not really 
care, but if I had one I would have found this information a bit 
uninformative.

The interesting question is whether the dev branch passes at least all 
tests as those when compiled with -O0, i.e. whether the optimization 
passes in the updated macports compiler are still causing trouble for 
(parts of) Erlang/OTP or not.

If not, either the compiler or Erlang/OTP needs fixing. Till then I 
would recommend to all MacOS users to keep using -O0 anyway.
