Not necessarily - however, you can be sure by using the "-O0" flag,
which is the implied default if you're using the "-g" flag.

Yes. Anybody compiling anything should use "-g -Wall" (or the
equivalent) until they're really happy with the results. Warnings are
useful. All warnings should be resolved, just in case. After running
this executable for a while, then you might try "-O" instead to see what
breaks (often lots of stuff, unfortunately).
