在Linux下写汇编总是会出现段错误是什么情况？

我这里是ubuntu x86-64，照着抄你的代码运行非常正常。

编译运行：

as run.s -o run.o

ld run.o -o run

./run

GDB调试也没问题

linux中执行c语言程序，段错误是怎么回事啊？？谢谢！！！

linux中的“段错误”通常是由内存分配失败或指针误指引起！

请检查程序中内存分配语句及其释放过程是否合理！

linux 段错误

出段错误是一件好事。。。说明你的代码在指针这里出了问题。。。最怕的是编译过了但是程序跑飞了的这种逻辑错误。。改都不知道怎么改。。。出段错误 你在程序里你觉得肯能有错的地方加上行打印 printf("%d\n",__LINE__); 或是隔几行加一个。。然后看程序死在那了。
