Yep, it's a bug; krbdev or krb5-bugs (where it'll actually get recorded in the bug database) would be the right place.
There's already code there that looks like it's supposed to be growing the buffer until it's big enough; apparently that's not working correctly. (And, why it doubles the size until it's at least as big as the size returned from the library routine, rather than just using the size returned by the search routine, I don't know....)
