You're misunderstanding.
ereport(..(errmsg("%s", _("hogehoge")))) results in
fprintf((translated("%s")), translate("hogehoge")).
So your change (errmsg("%s", gettext_noop("hogehoge")) results in
fprintf((translated("%s")), DONT_translate("hogehoge")).
which leads to a translation problem.
(errmsg(gettext_noop("hogehoge"))
works fine. You can see the instance in aclchk.c.
regards.
