patch 9.0.0013: reproducing memory access errors can be difficult Commit: https://github.com/vim/vim/commit/fa4873ccfc10e0f278dc46f39d00136fab059b19 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Jun 30 22:13:59 2022 +0100 patch 9.0.0013: reproducing memory access errors can be difficult Problem: Reproducing memory access errors can be difficult. Solution: When testing, copy each line to allocated memory, so that valgrind can detect accessing memory before and/or after it. Fix uncovered problems.
