BUILD METHOD USED:

I have used the traditional way of compilation.

CONTENTS OF $ACE_ROOT/bin/MakeProjectCreator/config/default.features
      (used by MPC when you generate your own makefiles):

cross_compile =3D 1
ssl =3D 1

AREA/CLASS/EXAMPLE AFFECTED:
          Cross Compilation

DOES THE PROBLEM AFFECT:
          COMPILATION?
          LINKING?
          EXECUTION?
             YES
          OTHER (please specify)?
                  Run time exception of Naming_Service and Event_Service

SYNOPSIS:

root@ml605:/# Naming_Service -ORBEndPoint iiop://141.89.52.137:12346 =20
-ORBDaemon
TAO (230|16384) ERROR: ORBInitializer Registry unable to find the =20
ORBInitializer Registry instance: Invalid argument
*** glibc detected *** free(): invalid pointer: 0x100107a8 ***
Aborted

or

root@ml605:/# Event_Service -ORBEndpoint =20
iiop://141.89.52.137:12347/portspan=3D1000 -n EventService -ORBInitRef =20
NameService=3Dcorbaloc:iiop:141.89.52.137:12346/NameService -ORBDaemon
TAO (231|16384) ERROR: ORBInitializer Registry unable to find the =20
ORBInitializer Registry instance: Invalid argument
Segmentation fault

in TAO version 2.0.0:

tao_cosnaming  -ORBEndPoint iiop://141.89.52.137:12346 -ORBDaemon

Nothing happens but when I run

root@ml605:/# tao_nslist -ORBInitRef =20
NameService=3Dcorbaloc:iiop:141.89.52.68:12346/NameService

again I see the same exception!

DESCRIPTION:

Whenever I run Naming_Service or Event_Service I face with =20
ORBInitializer exception and afterwards glibc complains for accessing =20
an invalid pointer.

For your information, I can run the simple client and sever Messenger =20
and it works absolutely without any problem. Moreover, I run ACE =20
Naming_Test, OS_Test, SString_Test and Svc_Config_Test and all of them =20
work without error report. If you would need I can send you their =20
generated log files.

REPEAT BY:

Always it occurs.

TAO Version 2.0.0 and 1.7.0 both have the same issues.

SAMPLE FIX/WORKAROUND:

Regarding the message from glibc for invalid pointer, I had doubt that =20
likely the source of problem is in wrong cross compilation of =20
something like ACE_TCHAR, but apparently those aforementioned ACE =20
tests prove that ACE library is OK. As far as, a typical client&server =20
CORBA application is working, hence I tried to follow some debugging =20
procedures to figure out where the source of problem might be. Then, I =20
tried to recompile the Naming_Service outside of ACE_wrappers. As a =20
result I noticed that whenever I comment out the "TAO_Naming_Server =20
my_naming_server_;" inside Naming_Service.h, and therefore, I exclude =20
all libraries except "-lTAO_PortableServer -lTAO_AnyTypeCode -lTAO =20
-lACE" the "CORBA::ORB_init (argc, argv)" in Naming_Service.cpp is OK =20
and working without exception. Otherwise, only by uncommenting the =20
"TAO_Naming_Server my_naming_server_;", the ORB_init fails!

Any kind of help to get rid of this issue is highly appreciated.

Thanks in advanced.

Ali
