cf5eacbf33 successful run of model generation test case, after assigning all internal variables a bogus value if they are unused 2015-12-03 20:58:54 -05:00

e010e7c0d6 add trace message to indicate which free variables are giving us trouble 
I think I'm onto the issue though

f5e94af784 check that both simplified expressions are concats in simplify_concat_equality() 
this seems to fix all the crashes but the solver takes forever to solve a really simple instance
with easy model generation, so I think something is still wrong
probably next I will go through and change std::map to obj_map, etc.

fc592fc856 fix for #291. The root issue is that the set of antecedents is recycled as a fixed object between routines. Antecedents that were already allocated for a Gomory cut got reset by the internalizer. This causes unsound bounds axioms to be created
