Apache 2.4.2 with PHP 5.4.4 crashes as soon as phpinfo() script is opened

Question

As soon as i open a phpinfo() script called version.php apache stops working. Here is the error.log file. My configuration (my local development machine):

• Windows 7 Home Premium x64 SP1 with latest updates
• Apache 2.4.2 win32 from Apache Lounge
• PHP 5.4.4 VC9 x86 TS from PHP For Windows
• php5apache2_4.dll (PHP 5.4.4) taken from Apache Lounge php5apache2_4.dll-php-5.4-win32.zip

PATH environment variable is PATH=C:\WAMP\Apache\bin;C:\WAMP\PHP and installation folders (unzipping) are:

• C:/WAMP/Apache
• C:/WAMP/PHP

Microsoft Visual C++ 2010 SP1 x86/x64 installed and updated. So everything looks fine to me. PHP integration in httpd.conf is:

# Integrazione PHP
LoadModule php5_module "C:/WAMP/PHP/php5apache2_4.dll"
PhpIniDir "C:/WAMP/PHP"
AddType application/x-httpd-php .php

<IfModule dir_module>
    DirectoryIndex index.html index.php
</IfModule>

Answer 1

I don't assume that PHP uses the PATH variable to resolve the path of the extensions. So try adding the whol path in the extension_dir variable like

extension_dir = C:/WAMP/PHP/ext

Answer 2

I've seen PHP crash Apache on phpinfo() before when:

1. I was using PHP as a FCGID process and it was not configured right.
2. I was using one of the opcode caches such as APC.

Try removing the loaded PHP modules/extensions one-by-one to see if one of them is causing this.
