commit https://github.com/vim/vim/commit/b9644433d2728e99fab874e5e33147ad95d23a31 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jul 19 12:33:44 2016 +0200 patch 7.4.2068 Problem: Not all arguments of trunc_string() are tested. Memory access error when running the message tests. Solution: Add another test case. (Yegappan Lakshmanan) Make it easy to run unittests with valgrind. Fix the access error.
