Re: [Help-glpk] GLPK 4_23 internal error in call back

[ms]

Thanks for the quick response. My callBack is shown below. I am calling
glp_delete_prob(lp) only in main and not in the call back

 --------------------main program-----------------------------
                 ....
                ret = glpk423._glp_lpx_simplex(lp);
                ret = glpk423.glp_intopt(lp, piocp);//--piocp pointer to
param
                 ...
                glpk423.glp_delete_prob(lp);
                ....
--------------------------Call Back ----------------------------
        public void callBack(IntPtr tree, IntPtr info)
        {
            this.StatusText = "Gap = " + glpk423.glp_ios_mip_gap(tree) +
                " Reason = " + glpk423.glp_ios_reason(tree);
          if (glpk423.glp_ios_reason(tree) ==
(int)glpk423.glpk_reasonCode.GLP_IBINGO) 
          {  if (glpk423.glp_ios_mip_gap(tree) <= 0.05) 
                glpk423.glp_ios_terminate(tree); 
          } 
        }
