what is the difference between "export" proedure/function modifier

In theory, they should mean the same.
In practice, FPC currently only actually exports routines that are in
the "exports" section of a library, or that are marked as export *and*
that have been (re)compiled during the current compilation run (i.e.,
that were not compiled previous compilation and simply loaded from a
.ppu file). See http://bugs.freepascal.org/view.php?id=16070

Following code crashes if disable define use_export_section.
library lib;
{$mode objfpc}{$H+}
uses
Classes
{ you can add units after this };
{$R *.res}
{$define use_export_section}
procedure PrintHello; {$ifndef use_export_section} export; {$endif}
begin
WriteLn('Hello world');
end;
{$ifdef use_export_section}
exports PrintHello;
{$endif}
begin
end.
