That was enough, thanks. I tend to think about arm* devices whenever
network-console is involved; seeing that affect amd64 means I could try
and run some commands locally without having to deal with arch-specific

It seems crypt() is no longer declared as it used to, and we get
implicit function declaration warnings from gcc, which later explains
the segfault at runtime.

The declaration is guarded by __USE_MISC but #define'ing it doesn't seem
to be sufficient. I've decided to add a <crypt.h> include, which seems
to do the trick: gen-crypt no longer segfaults, and seems to return
suitable results on my amd64 machine:

    kibi@armor:~/debian-installer/packages/network-console$ ./gen-crypt foo

Source uploaded to the archive (1.81), then it'll get picked up by the
buildds[1] and later made available in daily builds. It'd be nice if you
could double check that the runtime within d-i is also fine.

Thanks again for the report & follow-ups (und vielen Dank zu Marc for
the initial forward from the user list).
