Operating system: Linux 2.4.22 Debian Woody
PHP version: 4.3.2
PHP Bug Type: mcrypt related
Bug description: Memory usage
Description:
------------
When I use the functions for encrypt some data, the memory that PHP uses,
doesn't get free. It gets more and more memory.
Reproduce code:
---------------
<?php
$key = '123456789012345678901234567890';
$iv = '12345678';
$nVeces = 100000;
$n = 0;
$td = mcrypt_module_open( MCRYPT_BLOWFISH, '', MCRYPT_MODE_CBC, '' );
while( $n < $nVeces ) {
$fichero = file_get_contents( "/tmp/hola" );
mcrypt_generic_init( $td, $key, $iv );
$fichero_enc = addslashes( mcrypt_generic($td, $textoPlano) );
unset( $fichero_enc );
if( isset($fichero_enc) ) echo "<b><h1>No pudimos destruir la
variable</h1></b><br />";
$n = $n + 1;
}
mcrypt_module_close( $td );
?>
Expected result:
----------------
A script that execute with a consume of less than 1MB of memory (with a
file '/tmp/hola' of 1kB).
Actual result:
--------------
An script that consumes more than 100MB, or more. A similar script with
other data, have been consumed more than 2000MB.
