Is there anything special flagwise that I would need to specify to tell 
it to include symbol and debug information? I've tried specifying -g 
but this information still doesn't seem to be included. A quick copy of 
the build of one of the tests to make sure I've got the flags right:

With the same set of flags, gcc includes debug information. Is there 
anything else I need to add to get LLVM to do this too?

Thanks,
