Not reproduced in 7.1,9
Nice way to handle errors - just wait till version gets out of support cycle ;)

PHP 5 does not have active support anymore (only security issues
would be adressed). So, can anybody reproduce this issue with PHP
7?

Confirmed still on 5.6.21
The content-type header criteria is not relevant.
You just need a post request with an empty body using php-fpm.
It does not happen with Apache php mod.

Not fixed in 5.6.10:
curl -X POST http://example.com/script.php

I experience the same problem with PHP 5.6.9 under Ubuntu 14.04 with no 3rd-party libraries
installed. Test script contains the following code:
<?php
echo 'ok';
?>
Request: curl --data "param1=value1" http://example.com/script.php
Response: ok
Request: curl --data "" http://example.com/script.php
Response:
<html>
<head><title>502 Bad Gateway</title></head>
<body bgcolor="white">
<center><h1>502 Bad Gateway</h1></center>
<hr><center>nginx/1.8.0</center>
</body>
</html>
PHP log contains the following:
[04-Jun-2015 00:54:07] WARNING: [pool www] child 16781 exited on signal 11 (SIGSEGV - core dumped)
after 45.570352 seconds from start
Setting always_populate_raw_post_data to -1 solves the problem.
