Subject: [PATCH] index-pack: fix buffer overflow caused by translations
Date: Sat, 16 Mar 2013 08:25:18 +0700 [thread overview]
Message-ID: <1363397118-16015-1-git-send-email-pclouds@gmail.com> (raw)
The translation of "completed with %d local objects" is put in a
48-byte buffer, which may be enough for English but not true for any
translations. Convert it to use strbuf (i.e. no hard limit on
translation length).

My bad, I should have checked this when I marked this string for
translation. At least recent Vietnamese translation triggers this.
