This is a glpk internal logic error--at the specified point l[k] must not be -DBL_MAX while it is, so the sanity check fails. > perhaps I can just delete this assertion in the source code and > recompile? No, removing the assertion will not help. Don't do that. Please (if possible) write your mip instance to a text file in mps or cplex lp format with glp_write_mps or glp_write_lp, gzip the file, and post it to me (not to the list). Thanks.
