valgrind报告gsoap中的内存泄漏

Valgrind正在检测Gsoap中的一些内存泄漏 . 这是一个非常基本的示例代码：

//file hr.cpp
#include "soapH.h"  
#include "ns1.nsmap"

int main()
{
    struct soap *soap_ = soap_new();

    soap_destroy(soap_);
    soap_end(soap_);
    //soap_done(soap_);
    soap_free(soap_);

    return 0;
}

要编译此代码，我使用：

g++ -D DEBUG -g -std=c++0x -o hr hr.cpp soapC.cpp stdsoap2.cpp

这些是Valgrind报告的内存泄漏：

我究竟做错了什么？我错过了任何指示吗？我已阅读gsoap文档和互联网，但我没有找到任何东西 .

非常感谢！
