Seems like you encountered a state where the path length may be more than the program (underlying -s function) could handle. I can easily reproduce it by creating a circular symbolic link on FreeBSD. After 32|33 levels, size is undef, resulting in Use of uninitialized value in adddition <+> ... message.

I will post the updated program -- unless somebody beats me to it -- to not follow symbolic links.

Update (later that day): Problem that i observed was due to circular symbolic links (unresolved till 3[23] levels); there was no problem w/ 60+ levels of directories.
