Subject: BUG/MINOR: uri-auth: fix possible null-deref in latest fix for leaks
X-Git-Url: http://www.kaiwu.me/postgresql/commit/?a=commitdiff_plain;h=aa2c7034e1a3303a2ba34fe750e65047f39f1988;p=haproxy.git

BUG/MINOR: uri-auth: fix possible null-deref in latest fix for leaks

Latest commit 2dfbc311a8 ("BUG/MINOR: uri-auth: avoid leaks on
initialization error") left a possible null-deref case which was
surprisingly only detected by certain compiler combinations. No
backport needed.
