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: ffffea8003b95c80, memory referenced.
Arg2: 0000000000000001, value 0 = read operation, 1 = write operation.
Arg3: fffff80002ade00c, If non-zero, the instruction address which referenced the bad memory
Arg4: 0000000000000007, (reserved)
