vector 内存泄漏？
#include <stdio.h>
#include <stdlib.h>
#include <vector>
using namespace std;
int main( void )
{
vector<int> ints;
for (int i=0; i<10; i++)
{
ints.push_back(i);
}
return 0;
}
上面的代码在linux下用ccmalloc工具检查出内存泄漏。

`------------------------------------------------------ vector?内存泄漏
------解决方案--------------------
估计是工具统计的时机不对。
[解决办法]
工具傻瓜化导致
