APPLICATION_VERIFIER_HEAPS_FIRST_CHANCE_ACCESS_VIOLATION (13)
First chance access violation for current stack trace.
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. To debug this stop identify the access address that caused
the exception and then use the following debugger command:
    !heap -p -a ACCESS_ADDRESS
This command will give details about the nature of the error and what heap block is
overrun. It will also give the stack trace for the block allocation.
There are several other causes for this stop. For example accessing a heap block
after being freed. The same debugger command will be useful for this case too. 
Arguments:
Arg1: 0000000000000000, Invalid address causing the exception. 
Arg2: 00007ff874d7331d, Code address executing the invalid access. 
Arg3: 000000000023fb40, Exception record. 
Arg4: 000000000023f650, Context record.
