Subject: Fix core in multi-line selection on OpenBSD
X-Git-Url: https://git.xinqibao.xyz/st.git/commitdiff_plain/eeae9b0ceef9e2fec4cb4f1132748c302e5ac702?ds=inline;hp=8ac0a5f872b0024bab161fa020126013724758ba

Fix core in multi-line selection on OpenBSD

OpenBSD 5.3 amd64 release version with the most current st
version from git, crash and dump core when selecting multiple
lines whith the cursor.  This happens, because on line 964
of st.c (gp-1)->mode is accessed, although gp is still
pointing at the beginning of the array term.line[y] (see
line 939 for initialization of gp).
