It will fix the current problem of bufp contents being changed by recursive call, but we still have a danger of Lisp code being called in re_compile_pattern, which may lead to relocation of string data pointed by the arg "pattern". So, I think we must avoid any Lisp calls within re_compile_pattern. --- Kenichi Handa handa@m17n.org
