Just wanted to follow up and close this thread. Everything is working now. I had initially reported the problem with SWIG in Mono2.x or higher. In fact my mono1.9 build was 32-bit, because I used the mono-installer. Because the installer wasn't available for 2.0 I had to compile from source, which resulted in a 64-bit build. As soon as I compiled my C++ project and swig bindings in 64-bit, everything ran fine.
