I was bit bothered that with all the talk about malloc it was never highlighted that not all memory needs to be manually freed: local (stack) variables are quite safe, why it is a common pattern to give pointers of local variables to functions to store their results in. There are some common exceptions for this when you just need to call malloc, but these should be treated as exceptions.
