            Bug ID: 89187
           Summary: ICE in initialize_argument_information, at
                    calls.c:2023
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: marxin at gcc dot gnu.org
  Target Milestone: ---
              Host: x86_64-pc-linux-gnu
            Target: s390x-linux-gnu

Following code is causing ICE:

$ cat ice.C
template <typename a, int b> struct c {
  typedef a __attribute__((vector_size(b))) d;
};
template <typename a, int b> using e = typename c<a, b>::d;
template <typename a> using f = e<a, 4>;
struct g {
  g(f<int> h) : i{h[3]} {}
  g j() { return i; }
  f<int> i;
};
struct {
  g k();
} l;
class m {
  void n() const;
};
void m::n() const { l.k().j(); }
