I will add another: 4) Use hardware that supports bounds checking. OK This isn't an option for most of us since most HW architectures that we are currently stuck with don't implement bounds checking.
Perhaps you're not aware of it, but the x86 architecture does implement bounds checking. It even has a built-in BOUND instruction to do it! And... guess what? Most programmers don't know it exists. The x86 also has segmentation, which keeps pointers from going out of range. Unfortunately, OS implementors routinely turn segmentation OFF, perpetuating all of the many problems. We must insist that they stop doing this. Current CPUs are more than fast enough to handle the overhead. --Brett
