Hi,

I'm trying to compile a package containing an abstract remote type with
gnat 4.4 (using debian package from unstable amd64 and powerpc arch) at
the line declaring an access to the type I get this message :

events_receivers.ads:27:09: expected type
"Ada.Streams.Stream_Element_Offset"
events_receivers.ads:27:09: found type "Standard.Long_Integer"

The offending code :
with Ada.Streams;

package Events_Receivers is
   pragma Remote_Types;
   type Supported_Events_Type is (Log4ada_Event, String_Event);
   type Events_Receiver_Type is abstract tagged limited private;
   type Events_Receivers_Class_Access is access all
Events_Receiver_Type'Class; -- this is line 27
...

The same code with gnat gpl 2009 compile without problem

Does somebody already have experimented such behaviour ?

Thanks in advance, xavier
PS: the command line for the offending compilation :
