Is there an easy way to reproduce this? Which source code in particular
is build, where did it come from (debian source package or a particular
upstream release?), what are the specific build steps and how are the
particular testcases run? Can you show the steps that make things work
and which steps are different when things break?

Since there have been ~300 commits between 0.159 and 0.163 upstream,
it would be nice to narrow this down a bit more.
