bitcode file

I'm using LLVM 2.2 on debian Linux/x86. With the attached bitcode file (derived
from Noiz2sa, http://www.asahi-net.or.jp/~cs8k-cyu/windows/noiz2sa_e.html) I
get:

$ opt -f -o /dev/null reduced.bc -inline
Cannot take the address of an intrinsic!
        %savedstack1 = invoke i8* @llvm.stacksave( )
                        to label %savedstack.noexc unwind label %unwind831     
        ; <i8*> [#uses=1]
Cannot take the address of an intrinsic!
        invoke void @llvm.stackrestore( i8* %savedstack1 )
                        to label %_Z7yyparsev.exit unwind label %unwind831
