Out of range issue

&(temp_result[0]),

I have gotten a few out of range crashes here. I believe these should use the .data() method instead of &(vec[0]) to retrieve the memory location even when some of those vectors are empty. I also think there should be a general effort to change the rest of the instances as well. Should I create a PR with that?

Doesn't look like my email did anything so replying here:
Sure but please make it against master branch if possible, thanks!
