Confirmed, however compiling the second test in comment #0, namely

 integer, allocatable :: i(:)
 print *, NULL(i)
end

gives an ICE with 4.8.1 and trunk (4.9)

pr34547_1.f90:2:0: internal compiler error: in gfc_conv_expr_descriptor, at
fortran/trans-array.c:6423
  print *, NULL(i)

It compiles with 4.7.3, and gives the reported error with 4.6.4.
