Try this:
with Ada.Finalization;
package Trace is
type Location (S : access String) is limited private;
private
type Location (S : access String) is
new Ada.Finalization.Limited_Controlled with null record;
procedure Initialize (L : in out Location);
procedure Finalize (L : in out Location);
end Trace;
with Trace;
procedure Op is
S : aliased String := "Op";
Here : Trace.Location (S'Access);
begin
null;
end;
You have to declare the string object as aliased. You don't need heap for
what you're trying to do.
