Hi, I looked at the sourceforge windows socket code and noted

/ 
************************************************************************ 
*****
   SocketValid: Validate a given SocketPtr
************************************************************************ 
*****/
static int SocketValid(SocketPtr s) {
   if ((s != NULL) &&
       (s->privateSocketPtr != NULL) &&
       (s->sessionID == thisNetSession)) {
     return true;
   } else {
     FAIL();
     return false;
   }
}

This does not check if thisNetSession is null, the error condition will  
not be noticed and
running the code like
void sqSocketDestroy(SocketPtr s)
{
   privateSocketStruct *pss;

   if (!SocketValid(s)) return;

   pss = s->privateSocketPtr;

   /* close the socket if it is open */
   if(pss->s) {
     sqSocketAbortConnection(s);
   }

Will I'd bet cause the VM to crash on the dereference of  
privateSocketPtr, or on some other
call.
