'groups' is "long unsigned int" not "unsigned long long"

	long unsigned int groups = nladdr->nl_groups;

And nladdr->nl_groups is specified as "__u32"

So the size of the relevant bits is actually strictly 32-bit.

This makes also the "ULL" in your constant specification incorrect as
well.

So much crazy stuff going on here :-/
