I've just downloaded XAMPP 1.7.1 zip package.
After getting everything configured, I went to enable APC by uncommenting the "#extension=php_apc.dll" line in php.ini. After restarting apache I hit phpinfo() and I see that apc is loaded successfully. However, if I refresh the page apache will crash. Basically after restarting apache with APC enabled I get one visit to a particular page before apache crashes. As soon as I disable APC apache works again.
I'm running Vista x64. Anyone else have this problem or have any ideas?
