Bug description: memory leak in zend_execute.c and zend_operators.c
Description:
------------
When running a simple file that only instantiates objects using autoload,
there is a memory leak.
The leak appears to be caused by some combination of string concatenation
and exception throwing. The line that causes the leak is in
Pyrus/src/Pyrus/Registry/Sqlite3.php in the constructor:
if ($path && $path != ':memory:') {
if (dirname($path) . DIRECTORY_SEPARATOR . '.pear2registry' !=
$path) {
$path = $path . DIRECTORY_SEPARATOR . '.pear2registry';
}
}
The line "$path = $path . DIRECTORY_SEPARATOR . '.pear2registry';"
leaks the value "/usr/local/lib/php/.pear2registry" on my machine, and the
zval allocated for $path.
Reproduce code:
---------------
<?php
// run from checkout of http://svn.pear.php.net/PEAR2/all
function __autoload($class)
{
if ($class == 'PEAR2_Exception') {
include __DIR__ . '/Exception/src/Exception.php';
return;
}
$class = str_replace('PEAR2_', '', $class);
$class = str_replace('_', '/', $class);
include __DIR__ . '/Pyrus/src/' . $class . '.php';
}
$a = PEAR2_Pyrus_Config::current();
Expected result:
----------------
no output
Actual result:
--------------
