Subject: patch 8.0.0155: ubsan complains about NULL pointer
X-Git-Tag: v8.0.0155
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a216255a4faa91a15e7005ac319f2f62294f3f9e;p=vim

patch 8.0.0155: ubsan complains about NULL pointer

Problem:    When sorting zero elements a NULL pointer is passed to qsort(),
            which ubsan warns for.
Solution:   Don't call qsort() if there are no elements. (Dominique Pelle)
