问题描述

Seems AddressSanitizer detected heap-buffer-overflow but output not so clear as for example here .似乎 AddressSanitizer 检测到heap-buffer-overflow但输出并不像这里的示例那样清晰。

How can I get line at which overflow occurred?如何获得发生溢出的行？

How can I interpret this results?我如何解释这个结果？

It sounds like you need to set some environment variables before executing your program in order to get readable output: namely ASAN_OPTIONS , symbolize and ASAN_SYMBOLIZER_PATH (which assumes you have a suitable symbolizer).听起来您需要在执行程序之前设置一些环境变量才能获得可读的输出：即ASAN_OPTIONS 、 symbolize和ASAN_SYMBOLIZER_PATH （假设您有合适的符号）。 So something like this:所以像这样：

ASAN_OPTIONS=symbolize=1 ASAN_SYMBOLIZER_PATH=$(shell which llvm-symbolizer) ./a.out

It looks like you also copied the ANSI color codes into your output.看起来您还将 ANSI 颜色代码复制到您的输出中。 Here's a clearer version:这是一个更清晰的版本：

To get line numbers, you must specify the path to the llvm-symbolizer binary, either by having it accessible through the PATH environment variable, or by specifying its pathname directly in the ASAN_SYMBOLIZER_PATH environment variable.要获取行号，您必须指定 llvm-symbolizer 二进制文件的路径，方法是通过PATH环境变量访问它，或者直接在ASAN_SYMBOLIZER_PATH环境变量中指定其路径名。
