udf单核计算可以，双核编译正确，计算不能进行，怎么回事啊

潇叶飞扬

前面定义这个宏，DEFINE_EXCHANGE_PROPERTY(custom_drag2, cell, mix_thread, s_col, f_col)里面计算k_g_s_1, k_g_s_2，后面想按坐标分段取值，这是我的代码：
#if !RP_HOST                                                   /* 97*/
             begin_c_loop(c,t)
{
         Thread *t;
        cell_t c;        
         C_CENTROID(x,c,t);
               z=x[2];
         if(z<1.6)
          k_g_s=k_g_s_2;
        else
             if((z>=1.6)&&(z<=1.88))
      {
k_g_s=(-25*z/7+47/7)*k_g_s_2+(25*z/7-40/7)*k_g_s_1;
                 }
           else
                 k_g_s=k_g_s_1;        
         }                                          
  end_c_loop(c,t)
    #endif
        return k_g_s;

链接到case之后，计算一步就出现以下错误：unable to read the cmd header on the pmi context, Undefined dynamic error code.
