Bug Type: Date/time related
Operating System: Vista x64
PHP Version: 5.2.6
New Comment:
This happens for me too (PHP 5.2.6-4 with Suhosin-Patch 0.9.6.2 (cli)
(built: Sep 25 2008 01:14:32)). strangely enough it seems to cap off at
around 6k of memory usage:
<?php
echo "=== strftime() a lot ===\n";
$start = memory_get_usage();
echo "Start: ".$start."\n";
for($i = 0; $i < 10000; $i++ ) {
strftime("%d");
}
$end = memory_get_usage();
echo "End: ".$end."\n";
echo "Diff: ".($end-$start)."\n\n";
?>
produces
=== strftime() a lot ===
Start: 53264
End: 118644
Diff: 65380
while increasing the number of loops 10x has identical output. Also,
adding additional tokens (i.e. changing "%d" to "%d %d") increases the
leak, but adding spaces ("%d"=>"%d ") does not.

Same problem I'm afraid:
C:\php-latest>php.exe C:\php-gtk2\andy\symftest\strftime.test.php
=== strftime() ===
Start: 59072
End: 124488
=== date() ===
Start: 124488
End: 124456

Description:
------------
strftime() called many times results in increasing memory usage. date()
is OK. This is on Vista x64. PHP 5.1.6 (only version i have at the
moment) on linux does not exhibit the same problem.
Reproduce code:
---------------
<?php
echo "=== strftime() ===\n";
echo "Start: ".memory_get_usage()."\n";
for($i = 0; $i < 10000; $i++ ) {
strftime("%d");
}
echo "End: ".memory_get_usage()."\n\n";
echo "=== date() ===\n";
echo "Start: ".memory_get_usage()."\n";
for($i = 0; $i < 10000; $i++ ) {
date("d");
}
echo "End: ".memory_get_usage()."\n";
?>
Expected result:
----------------
End memory usage for strftime() should be close to Start memory usage.
Actual result:
--------------
C:\php-gtk2>php andy\symftest\strftime.test.php
=== strftime() ===
Start: 54384
End: 119800
=== date() ===
Start: 119800
End: 119768
