The dump window is displayed if the error detected involves memory corruption. The window contains the address of the corrupted memory and a dump (in hex and ASCII formats) of the affected region. The type of structure that is corrupted is named.
To check the integrity of memory, key system functions check the correctness of sentinel tags written at the head of important system structures. The sentinel tags are automatically written by the system functions that allocate and initialize the structures. If an incorrect tag is found for a structure, VV_ERR is set to indicate that the structure in question has been corrupted. The address of the corrupted structure and a dump of the structure is displayed (in hex and ASCII) when the dump window is displayed.
