In a larger project, I found that the PHP executable was crashing out altogether, appending no output to the logs, and offering minimal information. When I isolated what I suspected to be the problem, it was in fact the spl_autoload_register()/__call() combination. In isolation, it did not crash out spectacularly as in my project, however it still failed. While I marked this 5.3.9, these failures have been observed on 5.3.8, 5.3.9, and 5.4.0.RC3. While this is a bit of an edge case, I doubt that this is expected or acceptable behaviour, and have not been able to find mention of this elsewhere. Test script: --------------- <?php class Loader { public function __call($name, $arguments) { var_dump(get_defined_vars()); } } spl_autoload_register(array(new Loader(), 'load_class')); $foo = new Bar(); Expected result: ---------------- array(2) { ["name"]=> string(10) "load_class" ["arguments"]=> array(1) { [0]=> string(3) "Bar" } } Fatal error: Class 'Bar' not found in - on line 12 Actual result: -------------- Fatal error: Class 'Bar' not found in - on line 12 As you can see, while this test script made no attempt to actually load the class, it should at least be dumping the array before failing, as in the expected output. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60816&edit=1
