Bug description: memory leak when stream_context_create is used
Description:
------------
When stream_context_create() is used in conjunction with
file_get_contents() or other stream related functions that accept a context
parameter, memory is being leaked.
Reproduce code:
---------------
for ($i=0;$i<5;++$i){
$m0 = memory_get_usage();
file_get_contents('http://www.google.com', false,
stream_context_create(array()));
$m1 = memory_get_usage();
echo $m1-$m0,PHP_EOL;
}
Expected result:
----------------
X (where X is the memory increase for the first iterator)
0
0
0
0
Actual result:
--------------
X (where X is the memory increase for the first iterator)
384 (or something similar)
