--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> ---
Reduced testcase - albeit with different missing insn:

./gcc/cc1 -O2 reshape_generic-17.i

extern _Noreturn void runtime_error (const char *, ...) ;
void reshape_internal (long int rdim)
{
  long int shape_data[15];
  int seen[15];
  for (int n =3D 0; n < rdim; n++)
    if (shape_data[n])
      runtime_error("%ld", (long int) n+1);
  long int v =3D 0;
  for (int n =3D 0; n < rdim; n++)
     seen[n] =3D 0;
  if (seen[v] !=3D 0)
    runtime_error("");
}
