The present invention provides systems and methods for preventing software errors caused by address range or alignment errors. In architecture, a representative system includes a compiler that parses a program and further comprises a logic that generates a verification value for a block of code in the program, a logic that stores the verification value in the block of code, and a logic that inserts verification value instruction code into the block of code. The present invention can also be viewed as a method for preventing software errors in a program. A representative method operates by generating a verification value for a block of code in the program, and storing the verification value in the block of code. During execution of the program, a runtime verification value is generated for the block of code, and the block of code is executed if the verification value equals the runtime verification value, and generates an error message if the verification value does not equals the runtime verification value.
