我只是尝试使用GCC和

-fsanize=address

标志进行编译。当我运行我的程序时，地址消除器发现了一个缺陷，但是堆栈跟踪没有帮助。如何配置它，使其指向需要查看的源代码位置

==32415== ABORTING

这就是我的工作：

确保已安装llvm（包括llvm符号器）
导出以下变量
export ASAN_SYMBOLIZER_PATH=/usr/bin/llvm-symbolizer 导出ASAN\u符号器\u路径=/usr/bin/llvm符号器（替换为llvm SYMBOLER命令的正确路径）
现在按如下方式运行可执行文件（a.out）
ASAN_选项=符号=1 a.out

另一种选择是，这是我多年来在叮当声下一直在做的事情。通过

asan_symbol

管道输出符号。所以你应该做一些类似的事情：

/test.exe 2>&1 | asan|u符号

我在

/usr/bin

和

/usr/local/bin

中都有

asan_符号

：

$find/usr/-name asan*
/usr/bin/asan_符号
/usr/lib/llvm-3.4/lib/clang/3.4/include/sanitizer/asan_interface.h
/usr/local/bin/asan_symbol.py
/usr/local/lib/clang/3.5.0/include/sanitizer/asan_interface.h

我有两个副本，因为其中一个是通过

apt-get

（

/usr/bin/asan_-symbol

）安装的，我偶尔会从源代码中创建Clang（

/usr/local/bin/asan_-symbol.py

）

如果你没有拷贝，那么我相信你可以从谷歌代码中获取

一旦开始使用

asan_symbol

，您可能会遇到这样一种情况，即

asan_symbol

由于路径更改而找不到符号（例如，程序或库已从其生成位置复制到目标目录）。有关详细信息，请参阅Asan邮件列表上的

在kcc的回答中，他的意思是：

/test.exe 2>&1 | sed“s///g”| asan|u符号

（我想这就是我在测试博士后时必须做的事情）

Python有一个关于叮当声及其消毒剂的速成课程。它讨论诸如获取堆栈跟踪之类的主题。（我为Python项目编写了页面，以帮助他们将Clang及其消毒剂添加到其发布工程过程中。虽然已经有几年了，但我相信所有信息仍然适用）。

GCC 4.9.3不需要单独的符号

您有编译到可执行文件中的调试信息吗？@buc030我想是的，使用

-g3

标志。然后尝试addr2line，它是一个unix命令行实用程序，可以帮助您将地址转换为更重要的名称您使用的是哪个版本的GCC？常量被命名为an_symbolr_PATH，似乎对我有用。当你使用GCC编译时，棘手的一点是symbol=1。在叮当声中，这是可选的。请参阅我的要点：GCC（上文4.9.3）不再要求使用asan时禁用哪些标志？ ASAN_OPTIONS=symbolize=1 a.out
