Ok, I have found the bug more specifically.

You will need the cgi-fcgi command util from ubuntu/debian package: libfcgi0ldbl

Run fcgi server in dir with bugs76086.php script

PHP_FCGI_CHILDREN=1 php-cgi -b 127.0.0.1:9000

Then send a request from cli:

SCRIPT_NAME=bug76086.php SCRIPT_FILENAME=bug76086.php REQUEST_METHOD=GET cgi-fcgi -bind -connect
127.0.0.1:9000

returns (from cgi-fci command, not terminal running php-cgi):
PHP Warning:  file_put_contents(): Only 0 of 2 bytes written, possibly out of free disk space in
C:\Users\chris\bug76086.php on line 5

I only get the error when running via fast-cgi. I am not sure how to reproduce this without running
a webserver.

Thanks for the report. I see this when running your snippet

$ php-cgi.exe bug76086.php 1>nul
Error Occurred

How exactly teh issue can be reproduced?

Thanks.

This problem only seems to be a problem when using php-cgi

Description:
------------
Can no longer output to STDERR using file_put_contents. Used to work fine in PHP 5.x.
Also Affects 7.1.x

Test script:
---------------
<?php

$msg = "Error Occurred\n";
file_put_contents("php://stderr", $msg);


Expected result:
----------------
Error Occurred written to console on stderr

Actual result:
--------------
Rather than stderr output error message, I get a warning:
Only 0 of 15 bytes written, possibly out of free diskspace in script.php on line 3
