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.
