Indeed, this would never work, because there is no pfNode default
constructor. And this is because it is an abstract base class.
I would even avoid std::vector<pfGroup> because you never know
when pfGroups are instantiated by the vector, maybe even before
pfInit.

This is probably because you did not compile using -O.
Some inlining is not performed without -O
If -O does not help, try -O2
