yade crash at startup if chunksize=1, cause in cylinder.cpp

[Bruno Chareyre]

When I compile per-plugin, I get this vtable problem.
Could it be because I'm declaring and inheriting in the same hpp?
I tried different things (like defining virtual destructors in class declaration) but couldn't fix it.
I couldn't really spot differences with other functors declarations.
Any suggestion?
