terminate called after throwing an instance of 'Ice::ObjectNotExistException'

Hi,

I am using Ice 3.2.1 with C++

After calling a remote function using a proxy to an object that might or might not be hosted at an Object Adapter, the program terminates, although I am catching and ignoring all exceptions.

Here's the client-side code.

try {
int moteData=this->myPrx->getData1();
...
...
}
catch(...)
{
//don't care, go on
cout<<"Ice exception"<<endl;
}

The server-side code eliminates the servant using OA->remove(IceID).

I don't know why terminate is called, since I need to either ignore it or react to the exception.

Thank you in advance

    Its not clear to me why you get this exception. I suspect you'll find that the problem lies somewhere in your code. To confirm this you could modify the hello world demo that comes with the Ice distribution. In demo/Ice/hello/config.client change

    Hello.Proxy=hello:tcp -p 10000:udp -p 10000:ssl -p 10001

    to

    Hello.Proxy=helloX:tcp -p 10000:udp -p 10000:ssl -p 10001

    Then run the client. You should get an ObjectNotExistException like so:

    august:hello matthew$ ./client
    ./client: Outgoing.cpp:422: Ice::ObjectNotExistException:
    object does not exist:
    identity: `helloX'
    facet:
    operation: ice_isA

    If you cannot work out what is causing your problem you should:
    - Upgrade to Ice 3.3 (we do not provide free support for older versions of Ice on these forums).
    - Create a complete, self-compilable example that demonstrates your problem and attach it to this thread.

    I found out that the program is only terminated at some points in the program, if I call a function of a non-existent proxy. E.g. At main(), just after creating the object adapter, and adding the servant to it. If I remove it again from the object adapter and call a function at its proxy, I just get the normal exception with no crash.

    I just cannot find out why at other points of the program it terminates. I might have something to do with the fact that I use many threads. I also tried to reproduce the problem with another small program but It didn't work, I just got the normal exceptions.

    I will continue trying to find the error, and reproduce it with Ice 3.3. Anyway here is the stack trace. Thank you for your help.
