I have a ~1.5MB data file which is simply dumped to screen using the following code: 
#!/usr/bin/perl -w

use strict;
use warnings;

eval {
    die 'insufficient arguments' unless @ARGV;
    open(IN, $ARGV[0]) or die "unable to open '$ARGV[0]'";
    while (<IN>) {
        printf "%4d:\t%s", $., $_;
    }
    close IN;
};
if ($@) {
    print "error:\t$@";
}

If I run this in an xterm specifying the data's filename as an argument, the script runs & terminates the xterm. When I run this script at the console it runs to completion as expected; my debugger knowledge is weak, but it appears to run fine there too. What should I be looking for in the debugger in order to determine the root cause? Thanks for any insight which can be shared.
