(In reply to Marek Polacek from comment #2)
> The ICE started with

But the 7.x ICEd on and rejected the original testcase:
template<typename ss> void hh() {  ss t; }
template<typename ss>
struct tt {     ss t;  };


template<int>
int f(void)
{
    constexpr char const* cc =3D __PRETTY_FUNCTION__;
    struct j{  char const* kk=3Dcc; };
    tt<j> y;
    hh<j>();
}

int t =3D f<1>();

GCC 8+ accepts the above code though.
So in summary, the ICE is a regression but the rejects valid is not and cou=
ld
be workaround by using a struct first?=
