Comment 18 for bug 2026757

Hello, I verified that Sergio's PPA contains the candidate upstream patch (upstream commit d290630d31f4517ab26392d00753d1397f9a4114). If the crash is still happening that probably wasn't the issue after all.

I see two possible ways forward here. One is classic git based debugging:

1. compile 2.86 from upstream git and verify that the crash happens
2. compile 2.89 from upstream and verify that the crash doesn't happen
3. use `git bisect` to find the the commit that introduced the bug.

If that's not practical [but we may have to bite the bullet here!], we could do some work guesswork after figuring out if the Ubuntu packaged dnsmasq 2.87 is buggy or not. That version is not available anymore in the Ubuntu archive, it has been in the archive at some point (in Lunar), and compiled debs are still available here:

https://launchpad.net/ubuntu/+source/dnsmasq/2.87-1.1/+build/24632779

So by testing those we'll be able to tell whether the bug has been fixed between 2.86-1.1ubuntu0.3 and 2.87-1.1 or not. You'll need to manually install those packages via `dpkg -i` (no need to mention that this is normally not recommended!).

I'd test some of this myself, but without a reproducer I won't be able to tell much.
