You should see in valgrind output where the uninitialised values are 
instanciated/used (provided you compiled with -g).
I guess -O0 avoids optimizations, so that valgrind gives accurate 
results (optimisation can reorganise loops and such), I didn't know it 
was a prerequisite here, but it is probably not a bad thing.
