Comment 4 Guillaume Rousse 2019-01-27 11:58:28 CET

I had a look at the code of syslog-ng 3.9.1, shipped in mageia 6. According to my understanding, the problem doesn't exist in that version, as there is no use of the freed pointer, contrarily to more recent version.

Resolution: (none) => FIXED
Status: NEW => RESOLVED

Cool, thanks!

Version: 6 => Cauldron
