No it isn't. It's very useful. One particular benefit is that by
testing with optimised code, you will expose bugs in your code that
will only show-up when the optimiser is enabled. Also, when building
with the optimiser enabled, you get a few extra warnings that don't
show up when the optimiser is turned-off (basically because GCC doesn't
do the necessary analysis unless it's optimising)... some of these
warnings are quite useful.
I do agree with the general point that it's easier to debug things with
optimisation turned off completely, but debugging with it enabled
certainly isn't "next to useless".
Kind regards,
Alastair.
