I get a Blue screen every now and then in my driver, running on Windows XP
64 bit.
Here are some details about the crash dump file generated.
I am wondering if it is a data type aligment issue or if it is a bad memory
access case.

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: fffffadffcebd010, memory referenced.
Arg2: 0000000000000000, value 0 = read operation, 1 = write operation.
Arg3: fffffadfe3ef08ea, If non-zero, the instruction address which
referenced the bad memory
address.
Arg4: 0000000000000000, (reserved)
