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

[Christian Ehrhardt ]

As a bonus of debugging this, the reproducible builds have fallen out as well.
The patch that I use works (that is what was tested above) and it is stable in its binaries across 10 builds:

  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.
