This crash in sphinx is a known, but unresolved dependency bug. :(
If you build again it will almost certainly succeed.
i have no error: http://builder.miwibox.org/data/10amd64-jochen/2016-10-19_18h43m44s/logs/llvm37-3.7.1_4.log
thanks for the feedback, it succeeded after turning off ALLOW_MAKE_JOBS.
sorry for the noise (:
FWIW, you probably didn't even need to turn off ALLOW_MAKE_JOBS. One reason it hasn't been fixed is that it's hard to trigger (I've hit it a few times over hundreds of builds).
