[Bug ada/26306] New: Use of volatile array with bounds determined at run time.

[Bug ada/26306] New: Use of volatile array with bounds determined at run time.

[ben dot midgley at ultra-datel dot com]

I have included the configure, and build command below. 

This seems really easy to reproduce, 
create and array of integer values (I am unsure if integer is significant)  
the upper bound of which is determined by a function call
declare the array as volatile

This error can be avoided by using a fixed size array or removing the volatile
from the array.

Arno, what follows is a simple bit of code which causes the assertion failure
described in tree.c, In constructing this it became apparent that the bug
report should read use of volatile array, within a record, with bounds
determined at run time. I hope this clarifies the issue. 

---scratch.ada--------

        with system; 
        with Interfaces.c;

procedure scratch is 

        -- to get a value for the upper bound of the array 
    type my_Integer is range -2147483648 .. 2147483647;

    for my_Integer'Size use 32;

        function GetArrayUpperBound return my_integer is 
        begin
        return 2;
        end GetArrayUpperBound; 

        some_value : my_integer := GetArrayUpperBound;

    type Gp_Element_Type is
    record
        Element : Interfaces.C.Unsigned;
    end record;


        type some_type is
       array
          (1 .. some_value )
          of
          Gp_Element_Type;

        type Aligned_Some_Type is
            record
                Value : aliased some_type;
            end record;          

    for Aligned_Some_Type'Alignment use 8;          

        an_aligned_type : aligned_Some_Type;   
        my_address : system.address; 

        -- remember volatile too 

    pragma Volatile (an_aligned_type);


        begin

                my_address := an_aligned_type.value( 1 )'address; 


        end scratch;

You built GCC with --disable-checking, which is not a good idea (in particular
with GCC >= 4.1, at a minimum you should use --enable-checking=release).

this bug is still present in trunk:
