I guess it's not implemented for this analysis!  That makes sense because
memdep is a lazy analysis, i.e. it only does something when a user of it
asks for some specific information.  As it doesn't do any analysis
spontaneously, there is no analysis result for it to print in your context.

Ciao, Duncan.
