Thank you for the pointer - that is a good recommendation for me. I  
know there are several places where I can benefit from that layout. I  
upgraded my intel compiler to 8.1.025 and the problem has gone away.

Regarding the shared_dynamic_cast - that is what I have been using  
all along to perform the equivalent of a dynamic_cast on shared_ptr  
objects. I've never seen your version :-) I just did a google on it,  
and found out pretty quickly that I am using a deprecated cast  
function. I now have two things to thank you for!

Cheers,
