google sanitizers小试牛刀

google sanitizers提供了几个代码bug检查工具，包含AddressSanitizer, ThreadSanitizer, MemorySanitizer。

• AddressSanitizer (detects addressability issues) and LeakSanitizer (detects memory leaks)
• ThreadSanitizer (detects data races and deadlocks) for C++ and Go
• MemorySanitizer (detects use of uninitialized memory)

小试牛刀：

• 代码

  #include <stdlib.h>

  int main()
  {
      char *p = (char *)malloc(10);
      return 0;
      // memory leak;
  }

• 编译命令 gcc test_memleak.c  -fsanitize=leak -o test_memleak.o
• 运行结果
