Replying to my own post: With your help I was able to localize the 
error. Now I wrote a simple test program which behaves as the original 
one: runs on the machines a) and b) and provokes the error on c). Here 
it is:

with Ada.Strings.Unbounded;

procedure testUBS is

    type TA is record
          name:		Ada.Strings.Unbounded.Unbounded_String;
    end record;

    type TB is record
       a:	TA;
    end record;

    function New_TB  (name: String:="")  return access TB is
    begin
       return new TB'
         (a=>TA'(name=>Ada.Strings.Unbounded.To_Unbounded_String(name)));
    end New_TB;

    b:	 access TB:= New_TB (name=>"Det");
    name: Ada.Strings.Unbounded.Unbounded_String;

begin
    name:= b.a.name;
end testUBS;
