The problem was that it called  comphelper::rng::uniform_real_distribution()
with two equal arguments, which is invalid use of that API, and causes the
current implementation to get stuck in a loop in the boost code. (I didn't
bother checking whether it is possible that the loop eventually will exit.)
Fixed with 4bb67e666b2ca36a5caa5c3f22d0f1e802db527e
and 1b226b02471f2fab5e5e6f79b6593636274d2320 .
