GNU汇编程序 - 当我更改字符串时程序中断

Question

我正在研究一些简单的GNU代码，只是尝试使用格式字符串和1个printf打印两个字符串。问题是当我将string1从“Equal Created Were Women All \ 0”更改为“我不喜欢使用Assembly \ 0”时，程序在打印两个字符串后中断，并说a.exe无效。

    # pgm that calls a user function

    # set up globals
    .text
    .globl _main
    _string:            .ascii "All women were created equal\0"
    _string1:           .ascii "Equal Created Were Women All\0"
    _format:            .ascii "%s\n%s\0"

    #the main() function - simply call user fn

    #push parameters, call function, clear parameters, return
    _main: 
            pushl $_string1
            pushl $_string
            call _printStr
            addl $4, %esp
            ret

    #function to print a string passed to it on the stack
    _printStr:
            push %ebp       #save old frame pointer
            movl %esp, %ebp   #set frame pointer
            pushl 8(%ebp)
            pushl 12(%ebp)
            pushl $_format
            call _printf
            addl $, %esp
            leave
            ret

以上是工作代码

    # pgm that calls a user function

    # set up globals
    .text
    .globl _main
    _string:            .ascii "All women were created equal\0"
    _string1:           .ascii "I do not like using Assembly\0"
    _format:            .ascii "%s\n%s\0"

    #the main() function - simply call user fn

    #push parameters, call function, clear parameters, return
    _main: 
            pushl $_string1
            pushl $_string
            call _printStr
            addl $4, %esp
            ret

    #function to print a string passed to it on the stack
    _printStr:
            push %ebp       #save old frame pointer
            movl %esp, %ebp   #set frame pointer
            pushl 8(%ebp)
            pushl 12(%ebp)
            pushl $_format
            call _printf
            addl $, %esp
            leave
            ret

这是破解码。我认为它不是因为字符串而破坏但我老实说我不知道​​从哪里开始。我以为我可能不会清理整个堆栈，但似乎不是这样。谢谢你的帮助。
