[omniORB] Omnipy-Omniorb crashes performing narrow operation.

[Jose Carlos Lopez]

Hello,

I have a problem with the current TAO Naming Service version  and the 
access from a python client from Solaris 2.9/2.8. I have compiled 
OMNIORB 4.0.4 and OMNIPY for Solaris 2.9 with GCC 3.4.2.

The problem comes when I try to access TAO Name Service(executing on 
Solaris 2.8) from a python client that is running on Solaris 2.8.  If
I use the  OmniORB naming service I have no problem. Neither If  I 
execute the python client on the PC. Neither if
I execute the same code from a client running linux.

The problem is caused by the following operation:   rootContext = 
obj._narrow(CosNaming.NamingContext)
and the result is  the abortion of the python client.


This is the ouput OMNIORB generates:

Someone has any idea about what the problem can be?

Thanks a lot for your help.
