I can reproduce this with the perls available via perlbrew at least as far back as 5.10.1:

#####
[p5p] 38 $ perlbrew use perl-5.10.1
[p5p] 39 $ perl -v

This is perl, v5.10.1 (*) built for x86_64-linux

Copyright 1987-2009, Larry Wall
[snip]

[p5p] 40 $ perl -d 122445-debug-me.pl

Loading DB routines from perl5db.pl version 1.32
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

main::(122445-debug-me.pl:4):	$DB::single=2;
  DB<1> c
Segmentation fault (core dumped)
#####
