Maybe I should quickly add a further lead: in the original code, we allocated
a vector by something like

  std::vector<int> v(gv.indexSet().size(0),0);

valgrind complained about "conditional jump or move depends on uninitialized
variables" somewhere in the contructor-call for v, which IMHO points to the
return value of gv.indexSet().size(0) being uninitialized.

Bye,
Jö.
