    I've got my Redhat RPM working and ACATS looks good but the following code fails horribly.

    with Text_IO;
    with Interfaces; use Interfaces;
    procedure Slice_Bug is

    subtype Slice_Type is String(1..4);

    function identity(A : in Character) return Character is
    begin
    return a;
    end identity;

    function Get_Slice return Slice_Type is
    begin
    return identity('a') & identity('b') & identity('c') & identity('d');
    end Get_Slice;

    begin
    Text_IO.Put_Line(Get_Slice);
    end Slice_Bug;

    I expect it to print abcd
    Instead it prints 4 garbage characters.

    I suspect a 4.0.2 bug and submitted a GCC bug report but there is always a chance there is just something wrong with the RPM I built.

    Can this be confirmed on another platform (mine is 32bit redhat 4)

      It has been confirmed (now) on bugzilla.
