PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except,
it must be protected by a Probe. Typically the address is just plain bad or it
is pointing at freed memory.
Arguments:
Arg1: bfffffe9, memory referenced.
Arg2: 00000001, value 0 = read operation, 1 = write operation.
Arg3: 830a2efe, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 00000002, (reserved)
