I was deep into stepping through the initialization and noticed that gdb
was using two different funtion_template.hpp files !   I think there is
conflict between my projects installation of 1.34.1 and the
RedHat-supplied 1.32.0. Now to find someone here with root access...

Does that seem reasonable? 

Thanks,
Randy

It sound to me like an order of initialization problem.
What version of boost are you using?  Can you try
stepping through the initializtion of the boost::function<...>
and watching the value especially of the vtable?
