--- Comment #5 from Ngie Cooper <ngie at FreeBSD.org> ---
This code's broken:

444         char *release = calloc(length, sizeof(char));
445         char *version = calloc(length, sizeof(char));
446         char *tmp     = version;
447         sysctlbyname("kern.osrelease", release, &length, NULL, 0);
448         char c = *release;
449         while(c != '.' && c != '\0') {
450                 *tmp++ = c;
451                 c = *(++release);
452         }
453 
454         free(release);

It's freeing the modified pointer to `release`, instead of the original
pointer.

Trivial fix. I'll send one out over fabricator soon.
