Re: [Bug-glpk] glpsol: crash on display

Hello Andrew,

the same error is in
PARAMETER *parameter_statement(MPL *mpl)

Please, move the following code to the end of the function:

      {  AVLNODE *node;
         node = avl_insert_node(mpl->tree, par->name);
         avl_set_node_type(node, A_PARAMETER);
         avl_set_node_link(node, (void *)par);
      }
      /* the parameter statement has been completely parsed */
      xassert(mpl->token == T_SEMICOLON);
      get_token(mpl /* ; */);
      return par;
}
