INT 0C - CPU-generated (80286+) - STACK FAULT
Desc:   this interrupt is generated in protected mode on a stack overflow or
          underflow, or if an inter-level transition or task switch references
          a stack segment marked "not present"; it is generated in real mode
          on accessing a word operand at SS:FFFFh
Note:   the 80286 will shut down in real mode if SP=1 before a push.  On the
          PC AT and compatibles, external circuitry generates a reset on
          shutdown.
