Hi All

CE2020 GNAT on macOS gets stuck on the following code:

with Ada.Numerics.Big_Numbers.Big_Integers;
use Ada.Numerics.Big_Numbers.Big_Integers;
procedure Stuck is
   A : array (0 .. 9) of Big_Integer := (others => 0);   -- Stuck
begin
   null;
end Stuck;

$ gnatmake -gnat2020 stuck.adb

The array initialisation (others =>0) is the problem. When I changed it to (0 => 0, others => 0) it compiles.

Is the problem reproducable on Linux and Windows compilers?

/Jesper

procedure Not_Stuck is
    A : array (0 .. 9) of Big_Integer := (others => To_Big_Integer(0)); 
   begin
    null;
end Not_Stuck;

I tested with a recent wavefront of GNAT Pro, and it compiles (and runs) without problem. So no need to report to AdaCore I would think.

FSF GCC 11.0.1 20210331 crashes (internal compiler error).

Both this and GNAT CE 2020 are OK with (others => Big_Integer'(0)).
