Well, my mileage varies.  I was doing the same as you suggest
initially.  But then I noticed that most of the testing and debugging
is done on the non-optimized version; by the time I got to debug the
optimized one, I was usually bored or sick and tired, and tended to
skip some of the tests.  So now I begin the debugging with the
optimized version and only go to unoptimized one if I can't find the
bug otherwise.

Besides, turning on optimizations will make GCC check the source for
additional problems, like variables that are used before they are
initialized, so at least -O is mandatory, I think.
