I had a similar problem a few weeks ago. In my case it was because I had
two versions of llvm installed as it had been upgraded but the old
version wasn't deleted, and the X server was linking to both of them for
some reason. Try

pkg info -x llvm

and see if that's the case for you. For me, simply using pkg delete on
the older version fixed the problem.

get a program right as had at one time appeared. It was on one of my
journeys between the EDSAC room and the punching equipment that the
realization came over me with full force that a good part of the
remainder of my life was going to be spent in finding errors in my own
programs.
