Problem appeared after this change
r216925 | jhb | 2011-01-03 20:28:30 +0200
Downgrading sys/dev/age to the previous revision (r213893 | marius | 2010-10-15 17:52:11 +0300) and recompiling sys/modules/age "solves" this problem -
age(4) works like before last commit

Problem proved to appear on amd64 r217222 and i386 r217258.
