Compiled with -O the results are the same as with -O2. (-O is the same as -O1)
According to the gcc man -O0 turns off all optimisation.

It's unfortunate that the person who has the best chance of tracking
down the bug(s), Bruce, is not seeing any of the problems :-(
I'm afraid I'm not going to be much help this week as the shift
I'm on leaves me little time to play with the workstation at home.
I'll be able to do test compiles but not much debugging.
