use the latest version of PHP (5.3.25) and latest version of APC (3.1.13),
just run this script and watch the memory usage of the php process
(please run with: php -d apc.enable_cli=1 )


while (true) {
    $file = 'file1.php';

if run with  -dapc.enable_cli=0, it does not leak memory.

Test script:

while (true) {
    $file = 'file1.php';

Expected result:
The memory usage should not grow.

Actual result:
The memory usage grows very quickly.

To stably re-produce the bug, we need create 2 files.
// file1.php, can be empty

// leak.php

while (true) {
    $file = 'file1.php';

then run: php -d apc.enable_cli=1 leak.php

hope this helps, thanks.

APC is no longer supported in favor of opcache that comes bundled with PHP, if you wish to use the user cache, then look at PECL/APCu.
