Not with PHP 5.6.40 on Windows. Actually, this doesn't look like
a Windows specific issue to me, but rather depends on whether
stderr is actually writable. Since php://stderr does not refer to
the multiplexed FCGI standard error stream[1], there may be no
stderr at all.
See also bug #79905.

That would be great, since we prefer to have a PHPT regression
test to go along with the actual bug fix, anyway.

I can't reproduce this on Linux, so this looks Windows-specific.

I am ONLY using the libfcgi0ldbl as a stand-in for running a webserver.
It fails exactly the same way using Apache with fastcgi, nginx with fastacgi and using a PHP fastcgi
client. If you prefer I can write an example that uses the fcgi client used by the php unit tests.
https://github.com/php/php-src/blob/master/sapi/fpm/tests/fcgi.inc
using the cgi-fcgi package just means the example is simple to try and run and with Bash for
windows, its easy enough to run it on windows too.

Thanks for the further info. libfcgi0ldbl is not a package from the PHP distribution. It is also
unlikely available on Windows. Thus, seems it's not a PHP bug. From what is shown, i guess
it's about the port doesn't get reused or similar. If there's a repro regarding PHP,
please post, otherwise it's probably to be marked as not a bug.
Thanks.

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
