[omniORB] Problem to narrow EventChannel on Windows

[RAHON Daniel]

Hello, 

We have some problem to narrow an EventChannel in C++ on Windows. 
We use OmniORB 4.0 and both Visual C++ 5.0 and 6.0. 
The Event Channel is created and binded on the name service by a JacORB
server. 
We also use a JacORB names service. 

Here is the code we use to get the event channel 
     CORBA::Object_var obj = nc->resolve(name); 
     eventChannel = CosEventChannelAdmin::EventChannel::_narrow(obj); 
It works fine on linux (with a server on linux or on windows). 

On windows "obj" in not nil but the _narrow generates an access violation
error. 

When I try to _narrow my own objects I don't have any problem. 

I also tried to dump the IOR of the eventChannel with the "nameclt" tools to
use a string_to_object method but the result is the same.

Does anyone already faced this problem? 

Many thanks. 
DR
