This is a commendable philosophy which, unfortunately, does not work
in practice.
Due to optimizations, binary code compiled with "-g -O2" does not
follow the source code. Stepping through a program with a debugger
(gdb) is extremely painful. Some variables are optimized out, some
functions get inlined, instructions are not in sync with source code.

For debugging, I compile my code with "-g" or "-ggdb" and no any
optimization flags at all. This policy serves me well.
