| Subject: | Publishing large message results to segmentation fault (core dump) |
Hey guys,
I came across an issue, where publishing large message results to segmentation fault.
Coro version 999 required--this is only version 6.55.
AnyEvent::RabbitMQ version 999 required--this is only version 1.22.
Here is a simple snippet of my code:
#!/usr/bin/env perl
use strict;
use warnings;
use Net::RabbitFoot;
my $rf = Net::RabbitFoot->new()->load_xml_spec()->connect(
host => 'localhost',
port => 5672,
user => 'guest',
pass => 'guest',
vhost => '/',
);
my $ch = $rf->open_channel();
$ch->declare_exchange(exchange => 'test_x');
$ch->publish(
exchange => 'test_x',
routing_key => 'test_r',
body => 'x' x 140_000,
);
The result:
$ perl rabbit.pl
Segmentation fault (core dumped)

Does anyone have a clue, what might be causing that? Reducing the message to 70k chars does publish without issue.
Thank you.
Kind regards,
