PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced.  This cannot be protected by try-except.
Typically the address is just plain bad or it is pointing at freed memory.
Arguments:
Arg1: fffff8040001003f, memory referenced.
Arg2: 0000000000000010, value 0 = read operation, 1 = write operation.
Arg3: fffff8040001003f, If non-zero, the instruction address which referenced the bad memory
	address.
Arg4: 0000000000000002, (reserved)
