Pretty much the first thing you learn when developing with gcc is to use
-O1 -Wall for compiling devel code. Gets all the warnings and doesn't
confuse gdb too badly. Once in a long while I'll recompile an
individual file with -O0 so that I can single-step through it more
easily, but 99.44% of the time I'd rather have the
uninitialized-variable warning.
