ICAD转换转换到vc2005下的问题

1.内存泄漏问题：
void IcadConvertResbufChainToMalloc(struct resbuf* rb)
{
struct resbuf* currRb = rb;
for (; currRb != NULL; currRb = currRb->rbnext)
{
short iType = ic_resval(currRb->restype);
if (iType == RTSTR)
｛
if (currRb->resval.rstring != NULL)
{
char* buf = static_cast<char*>(malloc(strlen(currRb->resval.rstring)+1));
strcpy(buf, currRb->resval.rstring);
//delete currRb->resval.rstring;//程序运行到这行就报错，不知为什么？！
currRb->resval.rstring = buf;
}
}
else if (iType == RTBINARY)
{
if (currRb->resval.rbinary.buf != NULL)
{
char* buf = NULL;
if (currRb->resval.rbinary.clen > 0)
{
buf = static_cast<char*>(malloc(currRb->resval.rbinary.clen));
memcpy(buf, currRb->resval.rbinary.buf, currRb->resval.rbinary.clen);
}
else if (currRb->resval.rbinary.clen = -1)
{

int bufLen = *((int*)(currRb->resval.rbinary.buf));
if (bufLen > 0)
{
buf = static_cast<char*>(malloc(bufLen));
memcpy(buf, currRb->resval.rbinary.buf, bufLen);
}
}
//delete [] currRb->resval.rbinary.buf;;//程序运行到这行就报错，不知为什么？！
currRb->resval.rbinary.buf = buf;
}
}
}
}
请教大侠快帮帮我吧！
2.程序在vc2003下运行正常，转到2005下，编译能通过，但是一运行到
void CMainWindow::DockControlBar(CControlBar* pBar, UINT nDockBarID, LPCRECT lpRect)
{
//CDockBar* pDockBar = (nDockBarID == 0) ? NULL :
// (CDockBar*)GetControlBar(nDockBarID);

CMDIFrameWnd::DockControlBar(pBar,nDockBarID,lpRect);
}就报错请问怎么解决啊！急，在线等！
