Access Violation Exception.

This is the most common application verifier stop. Typically it is caused by a buffer overrun error. The heap verifier places a non-accessible page at the end of a heap allocation and a buffer overrun will cause an exception by touching this page.

There are several other causes for this stop. For example accessing a heap block after being freed.

Parameter1 - Invalid address causing the exception

Parameter2 - Code address executing the invalid access

Parameter3 - Exception record

Parameter4 - Context record

Verifier Stop code 0002.

To debug: Identify the access address that caused the exception and then use the following debugger commands: !heap -p -a ACCESS_ADDRESS.
