672	Bug in the Vf2 implementations	Peter Madarasi	Alpar Juttner	"In [https://lemon.cs.elte.hu/trac/lemon/browser/lemon/lemon/vf2.h#L181 vf2.h line 181] and in [https://lemon.cs.elte.hu/trac/lemon/browser/lemon/lemon/vf2pp.h#L226 vf2pp.h line 226], we may index a `NodeMap` with `INVALID` --- to which we set a reference and do not use it later. The code seems to work as it is, but these could cause segmentation fault.

The attached patch fixes both issues.
