amreport segmentation fault

[brettowe]

on arch linux for a while now I've been seeing a segfault with amreport
see it happening with all my configs on 2 servers
doing a backtrace on it i get the following

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff7b20b24 in Perl_pp_formline ()

perl version info is
This is perl 5, version 20, subversion 0 (v5.20.0) built for x86_64-linux-thread-multi

amanda is on 3.3.6
and was compiled with that version of perl also if that matters
let me know if any more info is required

I installed perl-5.20.0 and I got the same issue.
The bug is in perl-5.20 or in our interface to perl.
