The error message indicates that the bytecode format produced by
llvm-gcc is not what lli expects. This can happen when your LLVM and
llvm-gcc versions do not match. I'm assuming from your command that
you're using llvm-gcc4. If you compiled this from the latest version of
llvm-gcc SVN repository, then you also need the latest version of LLVM
from the CVS repository.

Which versions of these tools are you using?
