Suspicious omnithread problem

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
