Description:
------------
Throwing exceptions in an overloaded offsetGet() functions seems to cause
segfaults in PHP 5.1.2.
Reproduce code:
---------------
<?php
class foo extends ArrayObject {
public function __construct($obj, $flags = 0, $iterator_class =
"ArrayIterator") {
}
public function offsetGet($key) {
throw new Exception("hi");
}
}
$test=new foo();
try{
$a=$test['bar'];
} catch (Exception $e) {
echo "got exception";
}
?>
Expected result:
----------------
I expect the output:
got exception
Actual result:
--------------
I get a segfault, with backtrace as follows:
#0 0x081cb2cd in spl_array_read_dimension_ex ()
#1 0x081cb35f in spl_array_read_dimension ()
#2 0x08309d27 in zend_fetch_dimension_address ()
