Do you get segmentation fault with GNAT run in Ada mode?
(Currently, this would mean options -gnato -fstack-check
and no -gnatp, I think.)

What happens if you name the access-to-String type used for
a component of Archive_t, i.e. something like

   type String_a is access String;
   subtype File_Name_a is String_a;

   type Archive_t is new Ada.Finalization.Limited_Controlled with record
     Name : File_Name_a;
     File : Stream_IO.File_Type;
   end record;
