以下程序为我代码内一部分，，不知道在调试运行中会崩溃呢。。求哪位大神解答。

sendmail.h文件

#pragma once  

#include <vector>

using namespace std;

struct SMailInfo //邮件信息  

{  

	char*   m_UserName;

	char*   m_UserPassWord;

	std::string   m_SenderName;

	char*   m_Sender;

	std::vector<std::string> m_vReceiversAddress;

	char*   m_Title;

	char*   m_Body; 

	char*   m_IPAddr;

	char*   m_IPName;  

	SMailInfo(){memset(this,0,sizeof(SMailInfo));}

	~SMailInfo()

	{}

};



class CSendMail  

{  

public:  

	CSendMail(void){	m_FileBuff=NULL;

	};  

	~CSendMail(void){	if(NULL != m_FileBuff)

		free(m_FileBuff);

	m_FileBuff=NULL;

	};  



public:  

	bool SendMail(SMailInfo &smailInfo)

	{

		memcpy(&m_sMailInfo,&smailInfo,sizeof(smailInfo));

		return true;

	}
