Can Anyone Help Me Debugging An Error?

Hello everyone,

I'm posting cause mostly need some help debugging a copy of 2.24b Sources that seems to crash after a few hours.

Last time it crashed gave some error about "memory could not be read... 0x0000000C" and I debugged it...here's information I could get...

It toke me this function in XSocket.cpp

int XSocket::iSendMsg(char * cData, DWORD dwSize, char cKey)
{
WORD * wp;
int i, iRet;

if (dwSize > m_dwBufferSize) return DEF_XSOCKEVENT_MSGSIZETOOLARGE; // Here's where the debug redirct me to

if (m_cType != DEF_XSOCK_NORMALSOCK) return DEF_XSOCKEVENT_SOCKETMISMATCH;
if (m_cType == NULL) return DEF_XSOCKEVENT_NOTINITIALIZED;

m_pSndBuffer[0] = cKey;

wp = (WORD *)(m_pSndBuffer + 1);
*wp = dwSize + 3;

memcpy((char *)(m_pSndBuffer + 3), cData, dwSize);
if (cKey != NULL) {//Encryption
for (i = 0; i < dwSize; i++) {
m_pSndBuffer[3+i] += (i ^ cKey);
m_pSndBuffer[3+i] = m_pSndBuffer[3+i] ^ (cKey ^ (dwSize - i));
}
}

iRet = _iSend(m_pSndBuffer, dwSize + 3, TRUE);

if (iRet < 0) return iRet;
else return (iRet - 3);
}

Here's some information that I could get too...

cData 0x0012ee68
-48

cKey 0 ''
dwSize 16
i 1
iRet 1240656

Here's the HGServer.opt - <a href='http://hb-celestial.be/HGserver.opt' target='_blank'>Download</a>

Any help will be appreciated...since I'm a bit loss here.

I had this kind of error when a pointer pointed to a wrong object.
And the seaminlly related debug function were absolutelly unrelated.

I had too this kind of error when some object overflown.
(calling ellement n°5 of a table of 3elelments.)
