c++ 这样的内存泄漏怎么解决？

[allmai_net]

typedef struct my_struct_{
std::string name;
std::string address;
}my_struct,*lp_my_struct;

class abc{
public:
abc();
~abc();

private:
my_struct packet_;
};

abc abc_;


程序结束时提示：
c:\program files (x86)\microsoft visual studio 11.0\vc\include\xmemory0 (592): std::allocator<std::_Container_proxy>::allocate
c:\program files (x86)\microsoft visual studio 11.0\vc\include\xstring (671): std::_String_alloc<0,std::_String_base_types<char,std::allocator<char> > >::_Alloc_proxy + 0xF bytes

这样根本就看不出来有没有内存泄露好不好？

楼上的意思是，贴出来的代码看不出来内存泄漏，他让你把有关内存泄漏代码发出来

[老王爱上猫]

还有其它代码吧， new后没delete？

[allmai_net]

显示泄漏的地方和关联的代码，我就没有用过new，malloc 之类的。 就像这样也会提示泄漏： class abc{ ..... public: std::string buffer_; } abc::abc():buffer_(){ } 然后我在其它地方这样用： abc inst; 然后退出程序，就会报上面的这个泄漏信息。

[景语]

#include <string>

typedef struct my_struct_
{
    std::string name;
    std::string address;
} my_struct,*lp_my_struct;

class abc
{
    public:
         abc(){};
         ~abc(){};

    private:
          my_struct packet_;
};



int main()
{
    abc abc_;
    
    return 0;
}

这样用没问题啊，我编译运行过了

[铖邑]

如果这样的代码都会内存泄露的话，那就只能是std::string的问题了

[Saleayas]

这只是全局变量析构的时间问题。不是泄漏。

[我看你有戏]

代码没问题啊

[leftbackfielder]

可能只是释放时间的问题. 你试一下,让string立即释放呢? string s; string().swap(s);
