Bug 594168 – sys-apps/logwatch-7.4.0_p170-r1 - /usr/share/logwatch/scripts/services/amavis - "Unescaped left brace in regex is deprecated" after upgrade to dev-lang/perl-5.22.2

• Status: RESOLVED FIXED
• Product: Gentoo Linux

After upgrading to dev-lang/perl-5.22.2 (from 5.20.2) I have start getting the following message from logwatch on every run:

 Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/^(CLEAN|SPAM(?:MY)?|INFECTED \(.*?\)|BANNED \(.*?\)|BAD-HEADER(?:-\d)?|UNCHECKED|MTA-BLOCKED|OVERSIZED|OTHER|TEMPFAIL)(?: { <-- HERE [^}]+})?, ([^[]+ )?(?:([^<]+) )?[<(](.*?)[>)] -> ([(<].*?[)>]), (?:.*Hits: ([-+.\d]+))(?:.* size: (\d+))?(?:.* autolearn=(\w+))?/ at /usr/share/logwatch/scripts/services/amavis line 2279.

This is happening on all of my "stable" amd64 boxes.

Same problem here. On two hardened amd64 boxes.

The problem is known on other distros, and some patches seem to exist :

Same problem here. Upgrading to sys-apps/logwatch-7.4.2 solved the problem.

same thing. can confirm this in sys-apps/logwatch-7.4.0_p170-r on x86 and amd64. sys-apps/logwatch-7.4.3 works fine. can 7.4.3 be stabilized please?
