Thanks for this Petr. Would you be able to share the script you've used, so that perhaps an upstream developer could recreate the bug? Mainly I wanted to chime in and say that (in addition to the other instance referenced), we found this in the NetworkManager testsuite in Ubuntu. I didn't come up with a nice reproducer at the time, but we did identify the same commit and we've reverted it in Ubuntu. I posted on the ML back then but we didn't get much traction and I didn't follow up very aggressively. http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2018q4/012709.html https://launchpadlibrarian.net/405377161/dnsmasq_2.80-1_2.80-1ubuntu1.diff.gz (the commit ID referenced in the changelog there seems or from somewhere else, it's the same patch) Cheers, -- Iain Lane [ i...@orangesquash.org.uk ] Debian Developer [ la...@debian.org ] Ubuntu Developer [ la...@ubuntu.com ]
