--- Comment #2 from Jan Vesely <jano.vesely at gmail.com> ---
I should have noted that my llvm git includes
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20131216/199497.html.

Without these patches the backtrace in clones.xml test looks like this:
Program received signal SIGSEGV, Segmentation fault.
