I'm not sure how to reproduce it, but I still have the lldb session open so I can get more info if desired. Unfortunately, I don't have gdb installed so I can't use xbactrace, but it doesn't look like that would be very useful anyway.

When did you check out your sources? Jan D. Right before I built, so on 2014-11-05. I’m not sure the exact commit I checked out, but it would have been one of the commits below (almost certainly the last). I’m using the git mirror, so I don’t know the bzr ids.
