(ch_base::m_ranger, cb_base::m_query): Remove. (ch_base::copy_headers): Split processing loop into analysis around which we allocate and use ranger and transform where we do not. (pass_ch::execute): Do not allocate/free ranger here. (pass_ch_vect::execute): Likewise. * gcc.dg/torture/pr103188.c: New testcase.
