#127: Infinite loop in lp_heuristics.c

--------------------+------------------------------
 If the option "generate_cgl_cuts" is set to zero, the solver goes to an
 infinite loop with some instances. An MPS file where this happens is
 attached. The loop (I think) is the one starting on line 1378 (for(int k =
 0; k < d_cnt; k++)) in lp_heuristics.c.
