That was my first guess as well. So I started playing around.
After I commented out the graph drawing, the segmentation fault went away.
That was probably because after I commented it out, it didn't need to read the array again
I am not sure about that though

graphviz::data::grapher
GraphViz::Data::Grapher(3pm) User Contributed Perl Documentation GraphViz::Data::Grapher(3pm)
NAME
GraphViz::Data::Grapher - Visualise data structures as a graph
SYNOPSIS
use GraphViz::Data::Grapher;
my $graph = GraphViz::Data::Grapher->new($structure);
print $graph->as_png;
DESCRIPTION
This module makes it easy to visualise Perl data structures. Data structures can grow quite large and it can be hard to understand the
quite how the structure fits together.
Data::Dumper can help by representing the structure as a text heirarchy, but GraphViz::Data::Grapher goes a step further and visualises the
structure by drawing a graph which represents the data structure.
Arrays are represented by records. Scalars are represented by themselves. Array references are represented by a '@' symbol, which is linked
to the array. Hash references are represented by a '%' symbol, which is linked to an array of keys, which each link to their value. Object
references are represented by 'Object', which then links to the type of the object. Undef is represented by 'undef'.
METHODS
new
This is the constructor. It takes a list, which is the data structure to be visualised. A GraphViz object is returned.
my $graph = GraphViz::Data::Grapher->new([3, 4, 5], "Hello");
as_*
The data structure can be visualised in a number of different graphical formats. Methods include as_ps, as_hpgl, as_pcl, as_mif, as_pic,
as_gd, as_gd2, as_gif, as_jpeg, as_png, as_wbmp, as_ismap, as_imap, as_vrml, as_vtx, as_mp, as_fig, as_svg. See the GraphViz documentation
for more information. The two most common methods are:
# Print out a PNG-format file
print $graph->as_png;
# Print out a PostScript-format file
print $graph->as_ps;
