It shouldn't.
But testing shows at least one bug which may have something to do with this:
sum(q,i,1,inf) => asks q pnz OK
sum(f(i)+q,i,1,inf),simpsum => inf (without asking whether q is pnz)
simplify_sum has the same bug (it is perhaps using simpsum?)
I have reported this as bug
1945954<https://sourceforge.net/tracker/index.php?func=detail&aid=1945954&group_id=4933&atid=104933>;
