Liferea massive memory leak

Description: Ubuntu 18.04.1 LTS
Release: 18.04

apt-cache policy liferea

  Installed: 1.12.2-1
  Candidate: 1.12.2-1
  Version table:

There is a massive memory leak in this particular version of liferea, which is fixed in the next upstream point release, 1.12.3:

The issue report upstream:
https://github.com/lwindolf/liferea/issues/633

The commit that fixed it (only two small lines of code):
https://github.com/lwindolf/liferea/commit/b74f050a7f9870c18b7ef46bb4ce647b5ac4b9fa

The full changelog for the next upstream point release:
https://github.com/lwindolf/liferea/releases/tag/v1.12.3

There are also other important issues that are fixed in 1.12.3 and subsequent versions.
Is it possible to upgrade liferea's packages on Bionic to the most recent upstream version? Or at the very least a backport of the fix for the memory leak.

As it is, Liferea's memory consumption starts climbing into the GiB's after a few days with a modest number of feeds. If not restarted, it could probably trigger an OOM error, and, before that point, it may cause severe performance degradation of the entire system due to eventually forcing the use of swap.

Thanks.

I am aware of this, but will the relevant fix be backported to Bionic?

[Paul Gevers (paul-climbing)]

Don't know, but I nominated this bug for Bionic and closed it as Cosmic is fixed.
