I attached a small and obvious reproducer

Unconstrained array in entity port is origin of the problem.

library ieee;
use ieee.std_logic_1164.all;

entity reproducer is
	port(a:std_logic_vector);
end entity;

architecture test of reproducer is
begin
end architecture;

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture test of tb is
	signal sig: std_logic_vector(13 downto 0);
begin

	T:entity work.reproducer port map (a=>sig);
	
end architecture;
