Another strategy than can be a big help is to spend a little time thinking about what kinds of strings you are going to be using and how big they might be. And then sanitizing your program input based on those sizes. Find the too-long strings before they get into your program and before you start copying them around. The system I'm responsible for came into being as a set of programs on a Univac II and was a bunch of C and FORTRAN when I joined. Because of the need to pass data between C and FORTRAN programs/code, we had a set of 10-20 standard string sizes, based on what kind of text you had. We no longer write new code in either C or FORTRAN, but maintain the concept of standard sizes for our text. By specifying the kind of text (we also do this with numbers) in the design steps, we save far more time and effort than we spend over the entire SDLC.
