RC1: compiles fine, but crashes (Win2K)

Just running php.exe is enough to crash it... php4apache.dll also crashes. php.exe prints out: Content-type: text/html [a blank line] and then it crashes. Running a simple script like <?php phpinfo(); ?> also crashes PHP. During compiling, I got the following warnings: (...) zend_ini_scanner.c C:\php\php-4.1.0RC1\Zend\zend_ini_scanner.c(811) : warning C4102: 'find_rule' : unreferenced label (...) zend_language_scanner.c C:\php\php-4.1.0RC1\Zend\zend_language_scanner.c(5257) : warning C4273: 'isatty' : inconsistent dll linkage. dllexport assumed.
