Should have read: I think what you're trying to do just **isn't supported** at this time.

Which seems to imply you also won't know the flags it was compiled with thus making it difficult to setup the target machine to match.

But you're using an object file that explicitly expects __ImageBase  to be an IMAGE_DOS_HEADER  header.
The code generated could be attempting to access data from offsets/sections that aren't mapped properly.

Using clang/llvm tools to generate the object file, would probably be a better start.
It might make more sense to post on the LLVM list as to exactly what you are trying to accomplish and why it must be done this way.
