package QueueP is
generic (G_QUEUE_COUNT : positive := 1;
G_QUEUE_DEPTH : positive := 4096 / 8 + 5;
type G_DATA_TYPE;
function G_TO_STRING(data : G_DATA_TYPE) return string is to_string);
subtype t_queue_count is natural range 0 to G_QUEUE_COUNT - 1;
procedure test (x : t_queue_count);
end package QueueP;
package body QueueP is
procedure test (x : t_queue_count) is
begin
end procedure;
end package body;
-------------------------------------------------------------------------------
package pack is
constant C_QUEUE_COUNT : positive := 4;
constant C_QUEUE_MAX_SIZE : positive := 65535;
package C2hQueue is new work.QueueP
generic map (G_QUEUE_COUNT => C_QUEUE_COUNT,
G_QUEUE_DEPTH => C_QUEUE_MAX_SIZE,
G_DATA_TYPE => bit_vector(7 downto 0),
G_TO_STRING => to_string);
end package;
-------------------------------------------------------------------------------
entity issue894 is
end entity;
use work.pack.all;
architecture test of issue894 is
begin
tb: process is
variable v : natural;
begin
C2hQueue.test(v);
wait;
end process;
end architecture;

I have a strange error when creating an instance of a generic package. When I give a parameter an integer literal, it works. When I give the parameter an constant of the same integer, it creates an nvc error like this:
I wasn't able to create a MWE yet. The generic package instances are created in another package, here is an excerpt:
The public part of the QueueP package is as follows:
nvc Version:
I will post the code of an MWE if I'm successful to create one.
