这段代码为何会引起device栈泄漏

unsigned long  currTime = 0;
  unsigned long  authCode = 668346822; 
   unsigned short customerID = 3098;
   unsigned short customerVersion = 12624;
  int  num = 0;    

 unsigned  char  tmpBuf[64];
   void* pTemp = NULL;
  
  pTemp = ddnsMain_p->challengeStr + 6;   /*ddnsMain_p->challengeStr   为一个unsigned char 数组*/
   currTime = *((unsigned long* )pTemp);
/*debug Philip.Liu  China 2007-03-23*/
   DDNS_TRACE("peanutAuth() the time:/n%u/n",currTime);

 num = (currTime / 30) % 32;
   authCode = (~authCode) | (~currTime);   
   authCode = (authCode << (32 - num)) | (authCode >> num);
   /*debug Philip.Liu  China 2007-03-23*/
   DDNS_TRACE("peanutAuth() the authcode:/n%u/n",authCode);
  
   pTemp = tmpBuf + tmpLen;
 *((unsigned long* )pTemp) = authCode;
   tmpLen += 4;
  
   pTemp = tmpBuf + tmpLen;
   *((unsigned short*)pTemp) = customerID; 
  tmpLen += 2;
 
  pTemp = tmpBuf + tmpLen;
   *((unsigned short* )pTemp) = customerVersion;
   tmpLen += 2;
