Yes, it is strange that we do not delete libgroebner*.so because at
least we do attempt to. We cannot link libgroebner and its friends
CuDD and polybori dynamically sind that leads top double frees at
exit. Linking the static libraries instead avoids the problem. The
problem has been reported upstream, but I have not checked on its
status.
