Hello, I'am hanving some troubles with GNAT 3.01 for Windows NT. My environment is : Pentium Pro Windows NT 3.51 GNAT 3.01 MSVC 4.0 When I compile the following program using Text_IO and with the task RTL (the delay statement makes the task RTL linked with the program) I got an exception : "SYSTEM.ASSERTIONS.ASSERT_FAILURE" Without the delay everything is fine. What's the problem ? Thanks, Pascal. PS : I have checked that the LIBCMT (multithreads safe) is used. ----------------------------------- with Ada.Text_IO; procedure TestIO is begin Ada.Text_IO.Put_Line ("toto"); delay 1.0; end TestIO; --|------------------------------------------------------------ --| Pascal Obry Team-Ada Member | --| | --| EDF-DER-IPN-SID- Ing�nierie des Syst�mes d'Informations | --| | --| Bureau G1-010 e-mail: pascal.obry@der.edfgdf.fr | --| 1 Av G�n�ral de Gaulle voice : +33-1-47.65.50.91 | --| 92141 Clamart CEDEX fax : +33-1-47.65.50.07 | --| FRANCE | --|------------------------------------------------------------ --| --| http://ourworld.compuserve.com/homepages/pascal_obry --| --| "The best way to travel is by means of imagination"
