I just upgraded from Ice 3.1.1 to Ice 3.2.1. After the upgrade, one of my servers crashes whenever I try to shut it down. The shutdown is through icegridadmin (server stop <server name>).
Here's the crash stack:

The only extraordinary thing about the server is that it attempts to implement two interfaces. The management of all the memory is done through smart pointers:
Quote:
class MyApp : public Ice::Application
{
virtual int run(int argc, char* argv[]) {
//...initialization cut out
Ice::CommunicatorPtr ic = this->communicator();
// implementation of the two interfaces. Doesn't directly derive from anything
boost::shared_ptr<MyImpl> myImpl(new MyImpl(ic, <some args>));
// First interface, stores myImpl as a shared_ptr
MyI1Ptr p1 = new MyI1(myImpl);
// Second interface, stores myImpl as a shared_ptr
MyI2Ptr p2 = new MyI2(myImpl);
// Make the facets and activate them
Ice::ObjectPrx prx = adapter->add(p1, ic->stringToIdentity("myname"));
adapter->addFacet(p2, prx->ice_getIdentity(), "facetname");
adapter->activate();
// OK, the server is now up and running. Wait for it to shutdown.
ic->waitForShutdown();
}
};

Any help would be appreciated...
<Edit - added valgrind output>
For kicks I ran valgrind on the executable. The output is full of 'Invalid read of size 8' and 'Address is 24 bytes inside a block of size 48 free'd'. I've attached two of the pertinent reports, all caused on application exit.
