Just opened a bug report: https://bugs.php.net/bug.php?id=60042
The documentation does not indicate that autoloader functions registered with spl_autoload_register have to return anything, but if an autoloader other than the first one returns no value, PHP crashes. This is because of a dangling pointer condition. 'retval' is initialized at the top of spl_autoload_call but never re-initialized to NULL after the return value of each autoloader is destroyed. If the next autoloader has a return value, no harm is done, but if it does not the dangling pointer is destroyed again. Many authors of autoloaders have resorted to returning true or false in an educated guess at what they are supposed to do to avoid this problem, but in fact it's just a core PHP bug - when the code is working properly it doesn't actually care what the return value is. The patch is one line (: Wanted to bring this to folks' attention since it causes a lot of frustration for those using multiple frameworks, libraries, etc. all of which come with autoloaders. -- Tom Boutell P'unk Avenue 215 755 1330 punkave.com window.punkave.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
