Description:
------------
All is configured correctly and I can serve HTML pages grand but when I try to request a PHP page no matter how simple or complex the PHP code I get an internal server error in my browser.

PHP was working fine until I started using mod_fcgid. PHP works ok if I use 'LoadModule'.

In the Apache logs I'm getting the below error:
[fcgid:warn] [pid 816:tid 944] (OS 109)The pipe has been ended. : [client xxx.xxx.xxx.xxx:53392] mod_fcgif: get overlap result error
[core:error] [pid 816:tid 944] [client xxx.xxx.xxx.xxx:53392] End of script output before headers: index.php

And all I have in the index.php file is:

<?php
phpinfo();
?>

I'm running the the below:

- Apache 2.4.12 Win64
  - mod_fcgid 2.3.9
- PHP 5.6.5 x64

Apache Fcgid config being used:
FcgidInitialEnv PATH "C:/Program\ Files/PHP;C:/instantclient_12_1;C:/WINDOWS/system32;C:/WINDOWS;C:/WINDOWS/System32/Wbem;"
FcgidInitialEnv SystemRoot "C:/Windows"
FcgidInitialEnv SystemDrive "C:"
FcgidInitialEnv TEMP "C:/WINDOWS/Temp"
FcgidInitialEnv TMP "C:/WINDOWS/Temp"
FcgidInitialEnv windir "C:/WINDOWS"
FcgidIOTimeout 64
FcgidConnectTimeout 16
FcgidMaxRequestsPerProcess 1000 
FcgidMaxProcesses 50 
FcgidMaxRequestLen 8131072
# PHPRC is the location of the php.ini file
FcgidInitialEnv PHPRC "c:/Program\ Files/PHP"
FcgidInitialEnv PHP_FCGI_MAX_REQUESTS 1000

<Files ~ "\.php$>"
  AddHandler fcgid-script .php
  FcgidWrapper "c:/Program\ Files/PHP/php-cgi.exe" .php
</Files>


Test script:
---------------
<?php
phpinfo();
?>

Expected result:
----------------
Should render the PHP info page.

Actual result:
--------------
'Internal Server Error' page.
