关于一个Internal error,请键盘兄帮忙

我调用UF_MODL_create_fixed_dplane（），用UF_get_fail_message得到错误信息是Internal error :memory access violation~！
怎么修改这类错误？
  
代码：
            double dpoint[3];
  double direction[3];
  tag_t* dplane_tag = NULL;
  
  if(i_direction == 0)
    AfxMessageBox("请选择参考面所在平面！");
    
  switch(i_direction)
  {
  case 11:
    direction[0] = 0;
    direction[1] = 0;
    direction[2] = 1;
    break;
  case 22:
    direction[0] = 0;
    direction[1] = 1;
    direction[2] = 0;
    break;
  case 33:
    direction[0] = 1;
    direction[1] = 0;
    direction[2] = 0;
    break;
  default:
    break;
  }
  
  dpoint[0] = 0.0;
  dpoint[1] = 0.0;
  dpoint[2] = 0.0;
  
  int ret = UF_CALL(UF_MODL_create_fixed_dplane(dpoint,direction,dplane_tag));
  
  /*if(!UF_CALL(UF_MODL_create_fixed_dplane(dpoint,direction,dplane_tag)))*/
  if(ret == 0)  
  AfxMessageBox("create datum plane succeeded!");
  else
  {  
    char message[133];  
    UF_get_fail_message(ret, message );  
    AfxMessageBox(message );  
  }
