Abstract
Corruption of call stacks is detected by using guard words placed in the call stacks. A called function executing on a processor of a computing environment checks a guard word in a stack frame of a calling function. The checking determines whether the guard word has an expected value. Based on determining the guard word has an unexpected value, an indication of corruption of the stack frame is provided.
