patch 8.0.0307: asan detects a memory error when EXITFREE is defined commit https://github.com/vim/vim/commit/955f198fc546cc30a34361932d3f454a61df0efa Author: Bram Moolenaar <Bram@vim.org> Date: Sun Feb 5 15:10:51 2017 +0100 patch 8.0.0307: asan detects a memory error when EXITFREE is defined Problem: Asan detects a memory error when EXITFREE is defined. (Dominique Pelle) Solution: In getvcol() check for ml_get_buf() returning an empty string. Also skip adjusting the scroll position. Set "exiting" in mch_exit() for all systems.
