Subject: patch 8.0.1214: accessing freed memory when EXITFREE is set
X-Git-Tag: v8.0.1214
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4f1982800f0aff28df6875e718a786f6c4b11ad9;p=vim

patch 8.0.1214: accessing freed memory when EXITFREE is set

Problem:    Accessing freed memory when EXITFREE is set and there is more than
            one tab and window. (Dominique Pelle)
Solution:   Free options later.  Skip redraw when exiting.
