The Size of the following record is 112 on Linux, but 104 on Solaris.

type Something is record
   A : Packed_16;
   B : Packed_8;
   C : Packed_8;
   D : Packed_8;
   E : Packed_32;
   F : Packed_32;
end record;
pragma Pack (Something);

Where

type Packed_Byte is mod 2 **8;
for Packed_Byte'Size use 8;

type Packed_Bytes is array (Natural range <>) of Packed_Byte;
for Packed_Bytes'Alignment use 1;
for Packed_Bytes'Component_Size use Packed_Byte'Size;

type Packed_8 is new Packed_Bytes (0 .. 0);
for Packed_8'Size use 8;

and similar. Why is pragma Pack ignored?

TIA
