I still have no idea what could cause this (besides the unhelpful 
approach of downloading both tarballs and doing a diff) - and you didn't 
provide the bare minimum information to look into an issue, especially 
as this is a 3rd party build.

The basic bug reporting hints are on 
https://www.virtualbox.org/wiki/User_FAQ

In this case it's plain impossible say anything without VBox.log, and 
it's not there in the bug tracking system. We saw such errors when one 
used an unsupported/broken gcc version, but that's purely guesswork.

https://www.virtualbox.org/wiki/Mac%20OS%20X%20build%20instructions says 
which Xcode versions are usable. VirtualBox needs a proper gcc, LLVM 
won't work.
