patch 9.1.0149: null pointer member access when accessing 'winfixbuf' property Commit: https://github.com/vim/vim/commit/5131f224da93f2e042a4b22545ef62b1b2ab8460 Author: Sean Dewar <6256228+seandewar@users.noreply.github.com> Date: Mon Mar 4 19:09:26 2024 +0100 patch 9.1.0149: null pointer member access when accessing 'winfixbuf' property Problem: qf_goto_win_with_qfl_file may check if prevwin has 'winfixbuf' set without checking if it's valid first. Solution: Reverse the condition. Add a test, a modeline, and a missing CheckFeature.
