Date: Sun, 22 Jan 2012 23:30:59 +0100

Package: adduser
Version: 3.113
Severity: normal

Dear Maintainer,
trying to build a basic rootfs of armhf from x86 system with debootstrap i get this error when cron is setting up:
Setting up cron (3.0pl1-120+b1) ...
Can't set $0 with prctl(): Bad address at /usr/sbin/addgroup line 86.
dpkg: error processing cron (--configure):

related lines:
85    my $nogroup_id = getgrnam("nogroup") || 65534;
86    $0 =~ s+.*/++;
87   
88    our $verbose = 1;        # should we be verbose?

see this thread for further details,

http://lists.debian.org/debian-arm/2012/01/msg00062.html

i've  reported a bug to perl:

https://rt.perl.org/rt3//Public/Bug/Display.html?id=108792

honestly, i don't underestand a bit of what is this going about, i've just done my best to follow the instructions and report this correctly,
thanks

Iker
