tl;dr: die() hangs with high CPU usage in a certain environment with a lot of preparation.

Thanks for the report.

I got it down to

and further to

perl -we 'binmode(STDERR, ":encoding(us-ascii)"); warn "\x{ff}" x 100'

It turns out this (or something very much like it) was already reported upstream at https://github.com/Perl/perl5/issues/14362 .

I've added information to the upstream issue, but I don't expect a
quick resolution.

I had worked around in adduser anyway, I think the error message is a
bit less helpful now, but *shrug*

I really really appreciate the way you handled this report. It gave me
the impression that the hours I spent (on Minidebconf Hamburg) for a
not quite minimal reproducer were well spent. Thank you for your work!

Greetings
Marc
