CI 2.1-stable Active Record tries to escape db tables, fields and aliases with backticks, however it can trip up on queries such as...

	$this->CI->db->where("last_activity < {$expire}");

... which is an example actually used in the Session class in 2.1-stable. 
So out of the box you will get an SQL error when using database sessions.

Of course that should probably be rewritten: 

	$this->CI->db->where("last_activity <", $expire);

Put parameters on separate lines, and be consistent in the use of quotes: double quotes for params on the main tag, single quotes for params in the tag passed as a parameter:

{exp:stash:set_value 
	name="ref" 
	type="snippet" 
	output="no" 
	value="{exp:stash:get name='ref_{entry_id}' type='snippet'}" 
	parse="inward"
}
