Description:
------------
PHP crashes with the below code:
Reproduce code:
---------------
function __autoload($className) {
if($className == 'Foo') {
class Foo implements Bar {};
} else {
throw new Exception;
}
}
new Foo;
Expected result:
----------------
I don't know what to expect. The manual says, that you can't catch an
exeption thrown in an autoload function, but the crash only happens when
the autoload function gets called the second time. Below code doesn't
crash, but instead produces a Fatal error:
function __autoload($className) {
throw new Exception;
}
new Foo;
Actual result:
--------------
Faulting application php.exe, version 5.3.0.0, faulting module
php5ts.dll, version 5.3.0.0, fault address 0x0002358a.

@jani: sorry, i didn't make it clear. if Bar would have been defined, the autoloader wouldn't have to be called for the second time. but when it is called the second time, it is unstable, and i think it is the propagation of the exception that causes the crash. The exception can be caught inside the autoloader function: function __autoload($className) { if($className == 'Foo') { class Foo implements Bar {} } else { try { throw new Exception('message'); } catch(Exception $ex) {} } } new Foo; this code produces a fatal error: Fatal error: Interface 'Bar' not found in bug.php on line 5
