Hi, my program got a core dump with signal 11 @ omnithread lib. But I don't know why: #0 0x084baca9 in virtual thunk to CosNotifyChannelAdmin::_impl_SupplierAdmin::_dispatch(omniCallHandle&) () at /usr/include/omnithread.h:648 648 static omni_thread::init_t omni_thread_init; Any idea? Cheers, Christoph
