Downgraded to 3.4, now builds and starts without problems, but the errors are in bad condition - the function name is printed. Endiannees problem? andrey@sparc:~/dev/6$ sapi/cli/php -r 'file_get_contents("nofile.txt");' Warning: (nofile.txt): failed to open stream: No such file or directory in Command line code on line 1 The problem lies somewhere here : function.v is not NULL, but function_name_is_string is false. Otherwise function.s points to the right string, which is "file_get_contents" /* if we still have memory then format the origin */ if (function.v) { if (function_name_is_string) { origin_len = spprintf(&origin, 0, "%v%s%s(%s)", class_name, space, function.s, params); } else { origin_len = spprintf(&origin, 0, "%v%s%v(%s)", class_name, space, function, params); } } else { origin_len = spprintf(&origin, 0, "%s", stage); } Tony, please contact me if you need more information.Still fails, PHP6 is php6.0-200703191330, fresh from snaps andrey@sparc:~/dev/php6_head$ sapi/cli/php -r 'file_get_contents("nofile.txt");' Warning: (nofile.txt): failed to open stream: No such file or directory in Command line code on line 1 andrey@sparc:~/dev/php6_head$ sapi/cli/php -v PHP 6.0.0-dev (cli) (built: Mar 19 2007 15:40:33) (DEBUG) Copyright (c) 1997-2007 The PHP Group Zend Engine v3.0.0-dev, Copyright (c) 1998-2007 Zend Technologies
