The troublesome code from the valgrind log in iri.c (and the only major
change to iri.c since lucid) is from commit

Might be worth seeing if dropping that patch (which was only added to
avoid converting to UTF-8 twice, and seems kind of unsafe) and
rebuilding wget fixes the issue. If so, might be worth raising a bug
upstream so they can work out a proper fix.
