I got the permission so I will send the bitcode to you later. I am on Mac. Do I need to generate the bitcode on Linux for you to investigate? I am not sure if the bitcode from different platforms will be exactly same...
Now for the static linking, I wonder if you can determine what went wrong by just looking at the bitcode? If so that would be great and I then can also send the bitcode generated using LLVM_3.2...
