in this change, impl::extended_p_square_quantile_impl::probability is zero-initialized to silence -Wuninitialized warning from GCC-13.
despite that this variable is always initialized in impl::extended_p_square_quantile_impl::result(), it is still referenced by, for instance the copy constructor, which could be called before result() gets called. and GCC-13 rightly warn us like:
