Comment (by Kronuz):

 The cursor received in `ChertTable::find()`, `C_`, is a different object
 than that for which memory is allocated during
 `ChertTable::do_open_to_read`, so it remains with the old freed pointers
 during `ChertTable::close`. In other words, `ChertTable::C` is updated
 with new memory allocated, but `ChertValueManager::cursor` (the one
 calling `ChertCursor::find_entry()` -> `ChertTable::find()`) isn't so
 `ChertValueManager::reset()` needs a `cursor.reset(0);` (since the cursor
 will no longer be valid after the reopen) and `value_manager.reset();`
 should be called *after* opening the tables in
 `ChertDatabase::open_tables_consistent()`.
