You should only have to do your own marking if you have a smob you
defined that keeps a pointer to a SCM value.  Otherwise, the system
should do it for you.

Maybe you are keeping a pointer to a SCM value that is not protected
from gc?  After you allocate a compiled regexp, how do you make sure
that it never gets gc'ed?  Maybe all you need is a scm_protect_obj().

Sorry if this has already been discussed.
