Well, this is Debian testing and unstable what we are talking about.

If the Debian maintainers of Julia decided to use the latest LLVM compiler,
not the stable version that you recommend, I guess it's because they are
willing to help Debian as a whole to discover and fix any remaining LLVM
bugs (for example, this one if it were a LLVM bug) before the current
Debian testing becomes the next Debian stable.

In principle, this should be good for Debian and also good for Julia,
because it is this way that you will be able to recommend, say, LLVM 3.8,
when all of the bugs have been fixed and it's as stable as the older
LLVM versions.

Also, please note that I'm not speaking as an "end user" here. I'm just
a Debian maintainer with some interest on QA issues.

Thanks.
