HP-UX B.11.11 の方はいただいたパッチで直りました (make test まで確認しました)。
なんですが、HP-UX B.11.23 ia64 の方は以下のように SEGV するようになりました。

% make
  :
../ext/extmk.rb:106: [BUG] Segmentation fault
ruby 1.9.0 (2004-11-15) [ia64-hpux11.23]

sh: 26801 Abort(coredump)
*** Error exit code 134


再現させる最小のコードは以下のようになります。

% ./miniruby -e "/[1]*[\t]/ =~ ''"
-e:1: [BUG] Segmentation fault
ruby 1.9.0 (2004-11-15) [ia64-hpux11.23]
% ./miniruby -e "/[1]*[\n]/ =~ ''"
-e:1: [BUG] Segmentation fault
ruby 1.9.0 (2004-11-15) [ia64-hpux11.23]
% ./miniruby -e "/[1]*[\d]/ =~ ''"
% ./miniruby -e "/[1]*[\w]/ =~ ''"
% ./miniruby -e "/[1][\t]/ =~ ''"
% ./miniruby -e "/[1][\t]*/ =~ ''"
% ./miniruby -e "/[1]*[1]/ =~ ''"


デバッガで追ってみると OnigCodePoint の値が変になっているようです。
