--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This isn't the first PR where wide_ints are a problem for -W*uninitialized
warnings.  The primary problem is that generic_wide_int default ctor does
nothing and so does wide_int_storage default ctor, so keeps everything
uninitialized.
Do we want some non-default ctor say with some magic enum or whatever argum=
ent
that would zero initialize the whole storage?=
