ABSTRACT:
Methods and apparatus for identifying a first flow control instruction in an executing program, the first instruction being associated with a first program address at which program execution will continue after execution of the first instruction. A determination is made as to whether the first program address is protected. If the first program address is protected, a first alternate program address is substituted for the first program address such that program execution will continue at the first alternate program address after execution of the first instruction.
