This appears to be unrelated to reflection. Omitting the reflection
part, valgrind says:

Description:
------------
ReflectionParam object for 2nd parameter contains random value for name
property.
Test script:
---------------
<?php
class a
{
function b($a, $a)
{
$params = func_get_args();
var_dump($params, $a);
}
}
$c = new a;
$c->b('waa?', 'meukee!');
$reflectionClass = new ReflectionClass($c);
$params = $reflectionClass->getMethod('b')->getParameters();
var_dump($params);
Expected result:
----------------
array
0 => string 'waa?' (length=4)
1 => string 'meukee!' (length=7)
string 'meukee!' (length=7)
array
0 => &
object(ReflectionParameter)[4]
public 'name' => string 'a' (length=1)
1 => &
object(ReflectionParameter)[5]
public 'name' => string 'a' (length=1)
or exception/error..
Actual result:
--------------
array
0 => string 'waa?' (length=4)
1 => string 'meukee!' (length=7)
string 'meukee!' (length=7)
array
0 => &
object(ReflectionParameter)[4]
public 'name' => string 'a' (length=1)
1 => &
object(ReflectionParameter)[5]
public 'name' => string '<<insert random byte here>>' (length=1)
