AddressSanitizer (aka ASan) is a memory error detector for C/C++. It finds:

• Use after free (dangling pointer dereference)
• Heap buffer overflow
• Stack buffer overflow
• Global buffer overflow
• Use after return
• Use after scope
• Initialization order bugs
• Memory leaks

This tool is very fast. The average slowdown of the instrumented program is ~2x (see AddressSanitizerPerformanceNumbers).

The tool consists of a compiler instrumentation module (currently, an LLVM pass) and a run-time library which replaces the malloc function.

功能强大，使用方便，默认集成到了gcc 4.8；

集成方便，只需使用clang +一些flag，同时还可以做过滤：例如已知函数的泄露

性能还不错，只是源程序×2的占用，相比valgrind要好得多；

可跟gdb/objdump -ldS使用；
