--- Comment #13 from Alfie Richards <alfierichards at gcc dot gnu.org> --- As that removes one of the variadic arguments did you also add an extra argument to the call or lower the loop iterations to 24? Without those changes I get the negative number for the call to foo with and without preserve_none, but with them they both are fine. (https://godbolt.org/z/4oc9h9qqK)
