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.
Arg1: fffffffffa800823, memory referenced.
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation.
