A general protection fault (GPF) in the x86 instruction set architectures (ISAs) is a fault (a type of interrupt) initiated by ISA-defined protection mechanisms in response to an access violation caused by some running code, either in the kernel or a user program.
Attempting to write read-only memory (such as code segment) These in turn are often caused by programming errors that result in invalid memory access: Dereferencing a null pointer, which usually points to an address that's not part of the process's address space; Dereferencing or assigning to an uninitialized pointer (wild pointer, which points ...
Most CPUs are byte-addressable, where each unique memory address refers to an 8-bit byte. Most CPUs can access individual bytes from each memory address, but they generally cannot access larger units (16 bits, 32 bits, 64 bits and so on) without these units being "aligned" to a specific boundary (the x86 platform being a notable exception).
If you have any combination of "AOL" in your display name, the message won't go through. It is especially important to check your Mail settings for this if your account has been recently compromised, as hackers will often change your name to make it harder for you to use your account normally even after it's secured.

Typical causes include accessing invalid memory addresses, [a] incorrect address values in the program counter, buffer overflow, overwriting a portion of the affected program code due to an earlier bug, executing invalid machine instructions (an illegal or unauthorized opcode), or triggering an unhandled exception.
A null pointer is usually represented as a pointer to address 0 in the address space; many operating systems set up the MMU to indicate that the page that contains that address is not in memory, and do not include that page in the virtual address space, so that attempts to read or write the memory referenced by a null pointer get an invalid ...
If possible, ask the sender to resend the message to see if you can get the message a second time. Check for emails in your Spam folder. If you find emails in your Spam folder that don't belong there, you'll need to mark the messages as "not spam." 1. Sign in to AOL Mail. 2. Click the Spam folder. 3. Select the message that isn't spam. 4.
