unable to get XDebug to work

[genu]

I followed many different tutorials to install xdebug in php. I copied the dll and update the php.ini.

When I few php_info(), I see the xdebug is loaded, but if I refresh the page, or go to another page on the server, I get a message from windows that "Apache has stopped working"

in xampp control it says that apache is still running, but everytime I try to visit a page on the server I get that message "Apache has stopped working" I googled my problem, but I haven't found anybody experiencing this issue....
