[Coin-discuss] BCP: Purging local_cut_pool

[Francois Margot]

I got the following problem using BCP: At node A, I generate
cuts and put them in the local_cut_pool in BB_lp::generate_cuts_in_lp().
Then, in BB_lp::select_branching_candidates() I decide to fathom the
node and return BCP_DoNotBranch_Fathomed.

The enumeration continues and the next node that is processed includes
(incorrectly) the cuts generated at node A.

I apparently fixed this by adding

purge_ptr_vector(*(dynamic_cast<BCP_vec<BCP_lp_waiting_row*>*>(p.local_cut_pool)));

in the file BCP_lp_msg_node_send around line 324, inside the loop

if(keep == -1) {
  return -1;
}

but I don't know if this is the best place to do that. Note that the same
problem probably exists for the local variable pool.
