Types of storage violation
Storage violation can, for instance, consist of writing to or freeing storage not owned by the task.
A common type of storage violation is known as a stack buffer overflow where a program attempts to alter a memory location beyond its allocated memory.
Avoidance of storage violations
Storage violations can occur in transaction systems such as CICS in circumstances where it is possible to write to storage not owned by the transaction; such violations can be reduced by enabling features such as storage protection and transaction isolation.
Detection of storage violations
In systems such as CICS, storage violations are detected by the use of "signatures", which can be tested to see if they have been overlaid.
Some programming languages use software bounds checking to prevent these occurrences.
Some program debugging software will also detect violations during testing.
