If the source operand (divisor) is 0.
The signed result (quotient) is too large for the destination.
If a memory operand effective address is outside the CS, DS, ES, FS,
or GS segment limit.
If the DS, ES, FS, or GS register is used to access memory and it
contains a null segment selector.
If a memory operand effective address is outside the SS segment
limit.
If a page fault occurs.
If alignment checking is enabled and an unaligned memory
reference is made while the current privilege level is 3.
