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.

d9bafc3fba rewrite scoped_timer for linux 
The previous version was racy and could lead to crashes.
The timer could be deleted before the callback was called, making it execute on already freed memory

This new version is similar to Mac's. It spawns its own thread and uses pthread_cond_wait.
Care is taken for small timeouts to avoid races in the thread creation and timer destruction.
