Package: debian-installer
Followup-For: Bug #833599

Few more details.

I bissected the problem to start showing up in image

https://d-i.debian.org/daily-images/amd64/20160731-00:14/netboot/mini.iso


but not showing in


Comparing

https://d-i.debian.org/daily-images/amd64/20160731-00:14/build_netboot.log

and

https://d-i.debian.org/daily-images/amd64/20160801-00:15/build_netboot.log

with lines Unpacking I see this diff only:

$ grep Unpacking build_netboot.log  > /tmp/a1
$ grep Unpacking build_netboot.log.1  > /tmp/a2
$ diff /tmp/a1  /tmp/a2

Which is strange. As the 2.70 only contains translation fixes.

But it is possible that the compiler used or libc used was different than
previously, which somehow manifests here.
