创建一个unique_ptr来保存在免费存储中分配的数组的正确方法是什么？Visual Studio
2013默认情况下支持此功能，但是当我在Ubuntu上使用gcc版本4.8.1时，会出现内存泄漏和未定义的行为。

可以使用以下代码重现该问题：

#include <memory>
#include <string.h>

using namespace std;

int main()
{
    unique_ptr<unsigned char> testData(new unsigned char[16000]());

    memset(testData.get(),0x12,0);

    return 0;
}

Valgrind将给出以下输出：

==3894== 1 errors in context 1 of 1:
