As far as I remember exp_templates use alpha version of GC (for no special
reason; you should be able to switch to the latest stable release with no
problems). The messages you see are to my understanding debugging
messages, which are enabled in alpha, but disabled in stable version.
If still in doubt, please subscribe to gc...@li... and ask the
question there (I am not aware if this list is achived, possibly you can
find out at http://www.hpl.hp.com/personal/Hans_Boehm/gc/).
