commit https://github.com/vim/vim/commit/a216255a4faa91a15e7005ac319f2f62294f3f9e Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 8 17:46:20 2017 +0100 patch 8.0.0155: ubsan complains about NULL pointer Problem: When sorting zero elements a NULL pointer is passed to qsort(), which ubsan warns for. Solution: Don't call qsort() if there are no elements. (Dominique Pelle)
