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.
