我刚刚尝试使用 GCC 和 -fsanitize=address 标志进行编译.当我运行我的程序时，地址清理器发现了一个缺陷，但堆栈跟踪没有帮助.如何配置它以使其指向我需要查看的源代码位置?

I just tried compiling with GCC and the -fsanitize=address flag. When I run my program, the address sanitizer finds a flaw, but the stack trace is not helpful. How can I configure this so that it points to the source code locations I need to look at?

推荐答案

这对我有用:

  • 确保您已安装 llvm(包括 llvm-symbolizer).

  • 导出以下变量

  • Make sure you have installed llvm (including llvm-symbolizer).

  • Export the following variable

export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer

(替换为 llvm-symbolizer 命令的正确路径).

(replace with your correct path to the llvm-symbolizer command).

现在运行你的可执行文件(a.out)

Now run your executable (a.out for now) as

ASAN_OPTIONS=symbolize=1 a.out
