Hi! Thank you for the information about other related problem (I mean #1073346).
> I find surprising that you always get the infinite recursion problem. Before your message I had one failed build with infinite recursion problem in recent Debian Trixie i386 and one failed build with infinite recursion problem in recent Debian Trixie amd64. After your message I tried to reproduce problem with infinite recursion in Debian Trixie amd64 one more time. I removed folder with unpacked sources of wine and extracted source package archive again, then tried to build sources with "dpkg-buildpackage -b -uc" again. I got infinite recursion problem with ./make_vulkan again. I repeated these steps (from removing folder with unpacked sources) again and also got infinite recursion problem. So it looks that in my setup described earlier infinite recursion problem could be reproduced in a very stable way. I reproduced the problem 3 times for amd64 and 1 time for i386. > I wonder if you have tried building with sbuild using a chroot No, I didn't use sbuild. I used only dpkg-buildpackage as described earlier. > I wonder if you have tried <...> using less than 4 CPUs After your message I decreased cpus number in Vagrantfile from 4 to 1. Restarted VM with updated configuration. Checked in /proc/cpuinfo - I saw only 1 cpu here. And then I removed folder with sources, extracted them again and tried to build package with "dpkg-buildpackage -b -uc" again. And I got infinite recursion problem again. Now on 1 cpu in VM. So it looks like the problem is very stable in setup described earlier.
