Yes it does. Every extension for PHP is either compiled in thread safe
more, or non-thread safe mode. I think you're using a thread-safe xdebug
dll with a non-thread-safe PHP. I attached a NTS build for Xdebug for
PHP 5.2.5 or higher to this mail. Please make sure to use
"zend_extension" instead of "zend_extension_ts" in php.ini though.
