调试器和可执行文件之间的命令行参数列表差异
今天晚上我在某个敏感部位被它咬伤了，希望得到一些澄清。正如 karlphillip 在这个问题中所说，可执行文件将参数列表视为
Consider: ./program file.txt
argv[0] is "program"
argv[1] is "file.txt"
然而，在gdb调试器中，对于程序./lc1 f1.txt，arglist显示为
arg[0] is "/home/jason/Project 6/lc1"
arg[1] is "lc1"
arg[2] is "f1.txt"
Why the diffrepancy between the两个参数列表？
I had this bite me in a certain sensitive spot this evening, and would like some clarification. As karlphillip said in this question, the executable sees the argument list as
Consider: ./program file.txt
argv[0] is "program"
argv[1] is "file.txt"
However, in the gdb debugger, for the program ./lc1 f1.txt, the arglist shows as
arg[0] is "/home/jason/Project 6/lc1"
arg[1] is "lc1"
arg[2] is "f1.txt"
Why the discrepancy between the two arglists?

我无法重现该错误。你如何在 gdb 提示符下运行它？
我猜你有

I can't reproduce that error. How are you running it on the gdb prompt?
I'm guessing you have

That will reconcile with your normal execution.
