I reduced bounds_check_5.f90 to the following:

$ cat o2.f90
  INTEGER, POINTER :: x(:)
  logical :: l
  l = associated(x,x)
end
$ gfortran -fdefault-integer-8 -m32 o2.f90
o2.f90: In function ‘MAIN__’:
o2.f90:3: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676

The tree dump is very simple:

  logical8 l;
  struct array1_int8 x;

  x.data = 0B;
  l = _gfortran_associated (&x, &x) && x.dim[0].stride != 0;

I guess we are generating mismatched types somewhere in the && operator.
