写了个程序，需要长期运行，用pmap -d $PID查看到内存占用达到80M，而目标是控制在20M以内，故需要找出内存占用过多的原因。
占用物理内存： 83520K
mapped: 194864K writeable/private: 83520K shared: 0K
看pmap的结果，其中一个地址上占用了
00002aaaac06c000 65104 ----- 00002aaaac06c000 000:00000 [ anon ]
还有几个占用比较大的：
0000000040fd3000 10240 rw--- 0000000040fd3000 000:00000 [ anon ]
请教下有经验的前辈，如何才能根据前面的地址找出对应的源码行或者变量呢？比如上面占用了65104K虚拟内存的地址<00002aaaac06c000>，用什么办法查找出对应的源码行或者变量？
以下为pmap -d $PID的结果：
[root@rh5ora1 RHEL5.8]# pmap -d 26578
