I am also wondering about your confidence given the fact that there are obviously memory bugs during development... what gives you so much confidence that no memory bugs exist in released versions? Do you have an extensive test suite with valgrind /etc to ensure that there aren't any memory bugs before a release but some can slip in in intermediate versions? Or what do you do that gives you the confidence to say that there aren't any memory bugs in the released versions? Or what is involved in all the extra effort it takes to make a memory bug free c program?
