Example program which always causes a Segmentation fault:
#!/usr/bin/env perl
use common::sense;
use Net::Curl::Easy qw(:constants);
my $easy = Net::Curl::Easy->new({});
$easy->setopt(CURLOPT_URL, q(http://ifconfig.me/all));
$easy->perform;
$easy->reset;
$easy->setopt(CURLOPT_URL, q(http://ifconfig.me/ip));
$easy->perform;
