As for the string problem, we may have to modify the C-side functions to

have a look at how those strings are being used to suggest something more

The actual code that SWIG injects is
SWIGINTERN char *
SWIG_Guile_scm2newstr(SCM str, size_t *len) {
#define FUNC_NAME SWIG_Guile_scm2newstr
char *ret;
size_t l;
SCM_ASSERT (SCM_STRINGP(str), str, 1, FUNC_NAME);
l = SCM_STRING_LENGTH(str);
ret = (char *) SWIG_malloc( (l + 1) * sizeof(char));
if (!ret) return NULL;
memcpy(ret, SCM_STRING_CHARS(str), l);
ret[l] = '\0';
if (len) *len = l;
return ret;
#undef FUNC_NAME
}
As you can see, it's allocating a string on the heap and returning it, so
either the strings are already getting freed or we're already leaking them.
