Add [Optimization] at the start of the subject.  You'll want
to give details on why this is an middle-end optimizer problem.
This would include:
  1) The program runs correctly at -O0.
  2) The program fails at -O3.
  3) Include your program.
  4) Note the problem occurs on OSX and ppc, but can't be reproduced
     on i386 or amd64 for both linux and FreeBSD.
  5) In bugzilla, select optimization as the category.
