--- Comment #5 from darius@dons.net.au ---
It would appear to lie also, or at least I can't work out how it would free
anything :)

int
cgetclose(void)
{
        if (pfp != NULL) {
                (void)fclose(pfp);
                pfp = NULL;
        }
        dbp = NULL;
        gottoprec = 0;
        slash = 0;
        return(0);
}

int
cgetstr(char *buf, const char *cap, char **str)
{
...
        if ((mem = malloc(SFRAG)) == NULL) {
                errno = ENOMEM;
                return (-2);    /* couldn't even allocate the first fragment */
        }
...
