复制了 https://github.com/google/sanitizers/wiki/AddressSanitizerLeakSanitizer 中的示例，也按照说明编译了，但是完全没报错，这个什么情况？



[root@localhost tmp]# cat memory_leak.c

#include <stdlib.h>

void *p;

int main() {
  p = malloc(7);
  p = 0; // The memory is leaked here.
  return 0;
}


[root@localhost tmp]#
[root@localhost tmp]#
[root@localhost tmp]# gcc -fsanitize=address -g memory_leak.c -o memory_leak
[root@localhost tmp]#
[root@localhost tmp]#
[root@localhost tmp]# ./memory_leak
