__autoload() stream leak?

Hello, interals... Kind of stumbled onto this by accident. Some kind of FD leak in streams. In the current HEAD (and 5.0.0 RC1, I suppose, although I didn't specifically test that, just my CVS checkout)... class.one.php: <?php class one {} ?> class.two.php: <?php class two extends one {} ?> foo.php: <?php function __autoload($c) { require('bug_class.' . $c . '.php'); } require('class.two.php'); $a = new two; ?> jay@monty $ php5 foo.php Warning: __autoload(bug_class.one.php): failed to open stream: No such file or directory in /home/jay/bug/class.two.php on line 1 Fatal error: __autoload(): Failed opening required 'bug_class.one.php' (include_path='/usr/local/lib/php:.') in /home/jay/bug/class.two.php on line 3 /home/jay/setup/php/php5/main/streams/streams.c(371) : Stream of type 'STDIO' 0x4014dfac (path:class.two.php) was not closed Getting rid of the line that reads "require('class.two.php');" gets rid of the leak. The "bug_class." in autoload() is also not a typo; fixing that also gets rid of the leak (along with the warnings and such, too, obviously.) No idea what the problem is here, as my knowledge of the streams code is pitiful. J
