Late Detect Array Bounds Write (ABWL)

Memory Profiling for C and C++

An ABWL message indicates that the program wrote a value before the beginning or after the end of an allocated block of memory.

Memory Profiling checks for ABWL errors whenever free() or dump() routines are called, or whenever the free queue is actually flushed.

This message can occur when you:

Memory Profiling actually allocates a larger block by adding a Red Zone at the beginning and end of each allocated block of memory in the program. Memory Profiling monitors these Red Zones to detect ABWL errors.

Increasing the size of the Red Zone helps OneTest Embedded catch bounds errors before or beyond the block at the expense of increased memory usage. You can change the Red Zone size in the Memory Profiling Settings.

The ABWL error does not apply to local arrays allocated on the stack.

Note   Unlike PurifyPlus, the ABWL error in the OneTest Embedded Memory Profiling tool only applies to heap memory zones and not to global or local tables.
