Might be they wrote over internal structures, and some time later you'll get malloc crashing. Might be they wrote over something else that was already allocated, might be they wrote over unallocated space, might be that you got lucky and they wrote over something that nothing cares about. So what's going on? They wrote over something else! There's nothing stopping them from writing beyond what you've allocated, so they do. They just assume you know what you are doing, and go for it.Īs to why you didn't see a problem: Well, they wrote into that memory. strcpy/strcat have NO IDEA how much memory is at the other end of the pointer you gave them. The reason this works is that C has unchecked memory access.
