test_gcc_4_0_1.ads

 24 lines: No errors
compilation abandoned

test_gcc_4_0_1.ads:
package test_gcc_4_0_1 is

  type test1 is record
      b2 : BOOLEAN := TRUE ;
      b3 : BOOLEAN ;
      b4 : BOOLEAN ;
      b1 : BOOLEAN ;
    end record ;
    FOR test1 use record
      b1 at 0 range 00 .. 00 ;
      b2 at 0 range 01 .. 01 ;
      b3 at 0 range 02 .. 02 ;
      b4 at 0 range 03 .. 03 ;
  end record ;

  type test_A is record
      t1 : test1 ;
    end record ;
    for test_A use record
--      t1 at 0 range 0 ..  3 ;
      t1 at 0 range 1 .. 4 ;
  end record ;

end test_gcc_4_0_1 ;

-------------------------------------------

Additional informations:
1. if b2 has no default value, then compiling succeeds
2. if t1 starts at the first bit of a byte (commented line t1 at 0 range 0 ..  3
;), then compiling succeeds.
3. the compiling succeeds with gcc 3.3

Thank you for your help
With best regards
