--- Comment #2 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We ICE in tsubst
if (code == TEMPLATE_TYPE_PARM)
{
int quals;
/* When building concept checks for the purpose of
deducing placeholders, we can end up with wildcards
where types are expected. Adjust this to the deduced
value. */
if (TREE_CODE (arg) == WILDCARD_DECL)
arg = TREE_TYPE (TREE_TYPE (arg));
gcc_assert (TYPE_P (arg));
like a few other PRs. So it could be a dup.
