No, not at all. A SCM is either an immediate or a pointer into the
heap. They have to occasionally be messed with slightly on machines
where a pointer isn't just a linear address, but for the most part,
they're just pointers (albeit stored in longs, which could be causing
part of the confusion). The only place a leak detector should be
trusted to make a decent judgement about guile is where mallocs/frees
are taking place without becoming parts of scheme objects, and since
this is fairly rare, it's probably easier to do this by hand than to
have to wade through a lot of false alarms.
