list 命令打印一组行，但我需要一行，我在哪里以及可能发生错误的位置.

list commands prints a set of lines, but I need one single line, where I am and where an error has probably occurred.

推荐答案

我在调试时确实得到了相同的信息.虽然不是在我检查堆栈跟踪时.我认为您很可能会使用优化标志.检查此 链接 - 相关的东西.

I do get the same information while debugging. Though not while I am checking the stacktrace. Most probably you would have used the optimization flag I think. Check this link - something related.

尝试使用 -g3 进行编译，删除任何优化标志.那么它可能会起作用.HTH！

Try compiling with -g3 remove any optimization flag. Then it might work. HTH!
