=== AddressSanitizer (ASan) ===
AddressSanitizer是Google开发的内存错误检测工具，集成在Clang和GCC中。编译时添加`-fsanitize=address`选项即可启用：
<syntaxhighlight lang="bash">
g++ -fsanitize=address -g example.cpp -o example
</syntaxhighlight>

运行程序时，ASan会报告内存错误：
<pre>
==12345== ERROR: AddressSanitizer: heap-use-after-free on address 0x60300000eff0
    #0 0x4007a6 in main example.cpp:10
    #1 0x7f8e5a5b382f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f)
