cx执行到3的时候就崩溃了，咋回事_汇编语言

cx执行到3的时候就崩溃了，怎么回事？

Assembly code

assume cs:codea segment    dw 1,2,3,4,5,6,7,8,9,0ah,0bh,0ch,0dh,0eh,0fh,0ffha endsb segment    dw 0,0,0,0,0,0,0,0b endscode segment    start:    mov ax,a    mov ds,ax    mov ax,b    mov ss,ax    mov sp,16    mov cx,8    mov bx,0    s:    push [bx]    add bx,2    loop s    mov ax,4c00h    int 21h code endsend start

我debug加载后，t命令执行到cx=3的时候就崩溃了，怎么回事？

------解决方案--------------------------------------------------------
增大堆栈，比如: mov sp,100h
------解决方案--------------------------------------------------------
栈的空间不足，改大一点。
