Since your binary build works, the dynamic_cast / RTTI issues I'm seeing with my own build must be related to some combination of compiler choice and compiler flags. Is there anything special you're doing? How are you building OSG? Using CMake and the generated Xcode projects or something else?
I'm going to download you Simgear and FG Xcode projects now to see if I can spot any problems there. It's not an optimisation issue since it happens at -O0 as well.
