PAGE_FAULT_IN_NONPAGED_AREA (50)
Invalid system memory was referenced. This cannot be protected by try-except.
Typically the address is just plain bad or it is pointing at freed memory.
Arguments:
Arg1: ffffe10f04800014, memory referenced.
Arg2: 0000000000000000, X64: bit 0 set if the fault was due to a not-present PTE.
bit 1 is set if the fault was due to a write, clear if a read.
bit 3 is set if the processor decided the fault was due to a corrupted PTE.
bit 4 is set if the fault was due to attempted execute of a no-execute PTE.
- ARM64: bit 1 is set if the fault was due to a write, clear if a read.
bit 3 is set if the fault was due to attempted execute of a no-execute PTE.
Arg3: fffff8005cb8152c, If non-zero, the instruction address which referenced the bad memory
address.
Arg4: 0000000000000002, (reserved)
