VHDL: Arrays of unbounded elements not working correctly.

[mewais]

As the title says, use case:

type TestArray2DUU is array (NATURAL range <>, NATURAL range <>) of STD_LOGIC_VECTOR;

constant TestConst4 : TestArray2DUU(TestInt'range, 100 downto -100)(10 downto 0);                              -- Fails here with 2 errors.

Errors
