Abstract
Corruption of call stacks is detected by using guard words placed in the call stacks. A determination is made that a caller routine is to facilitate detection of corruption of stacks. Based on the determination, a store of a guard word in a stack frame of the caller routine is provided in the caller routine. The stored guard word is then used to detect corruption of the stack frame.
