commit https://github.com/vim/vim/commit/b9644433d2728e99fab874e5e33147ad95d23a31
Author: Bram Moolenaar <Bram@vim.org>

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.
