I think what you need is scm_gc_protect_object(). It takes one argument,
the object you want to protect from garbage collection. Unprotect it with
scm_gc_unprotect_object(). If you want to protect multiple objects, it
may be a better idea to place them in a vector or list and then protect
that (since protecting an object also protects everything it references).
