Summary: assert(true) increases memory_get_usage()
Status: Not a bug
Type: Bug
Package: *General Issues
Operating System: Windows 7
PHP Version: 5.4.12

I guess the same goes for this? The string 'true' is a new variable, that is
not
freed?
<?php
echo "assert(true)\r\n";
echo memory_get_usage(), "\r\n"; // 124448
assert(true);
echo memory_get_usage(), "\r\n"; // 124448
echo "assert('true')\r\n";
echo memory_get_usage(), "\r\n"; // 124448
assert('true');
echo memory_get_usage(), "\r\n"; // 124640 > 124448

The memory usage is increased not due to the assert(true) call, but because of
the variables used to store the memory usage. If you do something like this the
memory usage will not change:
var_dump(memory_get_usage());
assert(true);
var_dump(memory_get_usage());

Test script:

echo phpversion(), "\r\n";
$oldMemUsage = memory_get_usage();
assert(true);
$newMemUsage = memory_get_usage();
assert('$oldMemUsage == $newMemUsage');
echo 'OK';
