Otherwise, all seems OK. I can't reproduce this. The size of the shared_info changed with my tape drive related checkin from 2013-08-26, but your error message points to some older process still running, still using the previous DLL. Since the shared_info region continues to exist, any newer process using the new DLL will find that its idea of the sizeof shared_info doesn't match what has been noted in shared_info itself. Nothing else can explain this. What bugs me is that the change to the mtinfo structure (only the size of some members were affected) apparently didn't change the value of CURR_SHARED_MAGIC, but I don't think we can change this short-term.
