Bug description: Segfault when overriding class vars in foreach loop
Description:
------------
When assigning class variables to the results of a foreach
loop and using the variables inside the loop, I am getting
a segfault in 5.1RC3.
The problem occurs for class variables only. When doing the
same with local variables, it does not crash. It also does
not crash if the $this->vars["one"] is not used inside the
foreach loop.
If the foreach loop is used without setting the key for the
result it also won't crash, e.g.:
foreach $foo as $this->vars["two"]
instead of
foreach $foo as $this->vars["one"]=>$this->vars["two"]
won't crash.
I know code like this should never be written but Smarty
actually does a lot of stuff like this so it won't work
with 5.1.0RC3.
Reproduce code:
---------------
class x
{
function run()
{
$foo=array("0","1");
foreach ($foo as $this->vars["one"]=>$this->vars["two"])
var_dump($this->vars["one"]);
}
}
$x=new x;
$x->run();
Expected result:
----------------
in PHP 5.1.0b3:
int(0)
int(1)
Actual result:
--------------
in PHP 5.1.0RC3:
int(0)
NULL
