[Bug 2089779] Re: Buffer overflow in autopkgtest of wesnoth

[Christian Ehrhardt ]

I can recreate this locally, and really the new libsdl2 seems to be the
culprint.

Fine:
$ sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest --no-built-binaries --apt-upgrade --shell wesnoth-1.18_1.18.3-1.dsc -- qemu --ram-size=8192 --cpus 2 ~/work/autopkgtest-plucky-amd64.img

Triggers the issue (libsdl2 from proposed):
$ sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest --no-built-binaries --apt-pocket=proposed=src:libsdl2 --apt-upgrade --shell wesnoth-1.18_1.18.3-1.dsc -- qemu --ram-size=8192 --cpus 2 ~/work/autopkgtest-plucky-amd64.img


In those environments I can run the test directly via
$ /usr/games/wesnoth-1.18 -m --controller 1:ai --controller 2:ai --nogui --nosound --noaddons --nocache

  Repeats on reruns triggered by others.
  Blocks multiple migrations, atm
  - libsdl2
  - python3-defaults
  - boost1.83

  Unblocking all of these is surely worth it :-)
  I'll have a look tomorrow.
