Debugging

[James Colannino <james@colannino.org>]

Hey everyone.  I have a small program that I had written a while ago in 
C to help me study for my Spanish class.  I decided to rewrite some code 
recently being that I have a little more experience, and found that the 
program does not function properly when I compile with -O2 optimizations 
(I'm using GCC.)  It works as it should, however, when there are no 
optimizations.  How exactly should I go about debugging this and 
figuring out what code is causing the problem?  I could compile it with 
the -g option and feed it to GDB, but then doesn't debugging not work 
very well when you've done optimizations?  Is -O2 a low enough level of 
optimization that I shouldn't have a problem?  Debugging is one of the 
many things I know extremely little about, so I'm very in the dark 
here.  Any input would be greatly appreciated :)  Thanks very much in 
advance.

James
