Description:
------------
PHP removes a temorary object then tryes to assign into its property. As a result we have SIGSEGV.

Reproduce code:
---------------
<?php
function foo() {
  $x = new stdClass();
  $x->bar = array(1);
  return $x;
}
foo()->bar[1] = "123";
echo "ok\n";
?>

Expected result:
----------------
ok

Actual result:
--------------
crash and/or memory leaks

I don't get a segfault on Windows 5.1.1, Linux 5.1.1 (compiled on Ubuntu), or Linux 5.1.2 (compiled on Fedora).

As a side note, should that even be valid syntax? Shouldn't the left side of assignment only allow variables (other than the special language construct list())? Isn't foo()->bar[1] an expression, not a variable?

PHP always segfaults with this script if it is compied with --enable-debug.

Fixed in CVS HEAD and PHP_5_2.
