  59. Invalid system memory was referenced.  This cannot be protected by try-except.
  60. Typically the address is just plain bad or it is pointing at freed memory.
  61. Arguments:
  62. Arg1: fffffe0c4175afaa, memory referenced.
  63. Arg2: 0000000000000000, X64: bit 0 set if the fault was due to a not-present PTE.
  64.         bit 1 is set if the fault was due to a write, clear if a read.
  65.         bit 3 is set if the processor decided the fault was due to a corrupted PTE.
  66.         bit 4 is set if the fault was due to attempted execute of a no-execute PTE.
  67.         - ARM64: bit 1 is set if the fault was due to a write, clear if a read.
  68.         bit 3 is set if the fault was due to attempted execute of a no-execute PTE.
  69. Arg3: fffff806357d8046, If non-zero, the instruction address which referenced the bad memory
  70.         address.
