patch 9.0.1864: still crash with bt_quickfix1_poc Commit: https://github.com/vim/vim/commit/623ba31821a41acee7e948794e84867680b97885 Author: Christian Brabandt <cb@256bit.org> Date: Mon Sep 4 22:09:12 2023 +0200 patch 9.0.1864: still crash with bt_quickfix1_poc Problem: crash with bt_quickfix1_poc when cleaning up and EXITFREE is defined Solution: Test if buffer is valid in a window, else close window directly, don't try to access buffer properties While at it, increase the crash timeout slightly, so that CI has a chance to finish processing the test_crash() test.
