LoadLibrary内存泄露

[bingyu_2008]

我使用LoadLibrary方法加载一个资源文件“rc.dll”，结果用CodeGuard竟然检查出有内存泄露，当把LoadLibrary那行代码注释掉的时候就没有内存泄露了，不知道什么原因，各位帮忙分析一下，我的调用方式：
//.h文件中的声明
HINSTANCE FRcDll

//.cpp中的实现
TRcString::TRcString(LPCSTR szFile)
{
FRcDll = ::LoadLibrary(szFile);
}

TRcString::~TRcString()
{
if (NULL != FRcDll)
{
::FreeLibrary(FRcDll);
FRcDll = NULL;
}
}


以下是错误信息
Error 00120. 0x300010 (Thread 0x0100):
Resource leak: The memory block (0x15ADB50) was never freed

The memory block (0x015ADB50) [size: 200 bytes] was allocated with SysGetMem

[CppFile]

if (NULL != FRcDll)
不加这个看看

不加也是这样的，FreeLibrary(FRcDll);是执行过的，还是会报内存泄露

是不是你的DLL里本身就泄漏？

支持楼上，看你的dll本身是不是就有问题

很奇怪，我原来建的工程里面就不会出现这种情况，源文件和dll都是直接拷贝到新工程里面的，同时出现的还有另外一个问题，memcpy(&_buffer[index], &input[i], length - i);运行到这句的时候报下面一个错误pointer underrun，这个是网上下的一个md5文件里面的

Error 00139. 0x140100 (Thread 0x0250):
Pointer underrun: 0x0012F7F0, that is at offset 8 in local block
0x0012F7E8(=[ebp-0x14] @mtsuprj.exe:0x01:0015CD) (size 8).
memcpy(0x0012F878, 0x0012F7F0, 0x0 [0])

新建个工程，把这两个文件加进去，把内存检查工具打开后运行，然后再把Form里面被注释的代码释放掉运行，我是真的找不到内存泄露的原因了，请大家帮忙看看
