    * trans-array.c (gfc_array_allocate): Zero memory for all class
    array allocations.
    * trans-stmt.c (gfc_trans_allocate): Ditto for class scalars.

    * trans-stmt.c (gfc_trans_allocate): Before correcting a class
    array reference, ensure that 'dataref' points to the _data
    component that is followed by the array reference..

    * gfortran.dg/class_48.f90 : Add test of allocate class array
    component with source in subroutine test3.  Remove commenting
    out in subroutine test4, since branching on unitialized variable
    is now fixed (no PR for this last.).
