Bug #72024 [NEW]: microtime() leaks memory
From: maroszek at gmx dot net
Operating system: Windows 10 x64
PHP version: 5.6.20
Package: Date/time related
Bug Type: Bug
Bug description:microtime() leaks memory
Description:
------------
Just run the script and watch the memory consumption rise. It goes way
beyond the specified memory limit, therefore i suspect a simple memory
leak.
Not reproducable on 7.0.x.
Not reproducable on 5.4.x.
Bug must have been introduced with PHP 5.5. This is the first affected
version.
Test script:
---------------
<?
while(true) { microtime(); }
Expected result:
----------------
Steady memory consumption.
Actual result:
--------------
Right before max_execution_time occurs, php.exe is consuming a few
hundred megabytes of RAM.
