As I've indicated a couple of  times, I personally found an optimization
bug non-reproduceable on Linux (Mandrake). I believe linux kernel is, by
default, being  built with high  optimizations and linux  machines don't
fall all over because of that. This all suggests, that there are FreeBSD
specific  issues with  GCC. So  ``make that  all developers''  -- anyone
who  can construct  a meaningful  bug-report  should be  using the  high
optimization.  When such  bug-reports are  submitted, they  need to  get
serious  attention,  especially, when  there  is  evidence, the  bug  is
FreeBSD specific.
