Access violation in Kaleidoscope Chapter 4

Hi

I'm starting to use LLVM, in order to develop a compiler. I've been following the tutorials, but now I have a problem. In the kaleidoscope tutorial, chapter 4, I get a Access Violation in ExecutionEngine->getTargetData(). I tried to solve it, but with no success. Can you help me?

I'm using Visual Studio 2008.

Thanks in advance,
Paulo Matias
