Operating system:
PHP version: 5CVS-2006-01-11 (CVS)
PHP Bug Type: Scripting Engine problem
Bug description: Memory leak if exception thrown within switch
Description:
------------
A memory leak occurs if an exception is thrown within a switch($var)
block
The leak does not occur if the switch is made on a constant [eg
switch(5)]
Occurs in 5.0.5, but not in 5.1.1
It *does* however still appear in 5.0-CVS (2006-01-11) -- maybe the bug
was 'accidentally' fixed in 5.1; I couldn't find any reference to it in
the bugs list.
If it was a deliberatel fix in 5.1, can the fix be backported to the 5.0
tree too?
Reproduce code:
---------------
#!/usr/local/src/php5/php-5.0CVS/php-src/sapi/cli/php
<?
try {
$x = 0;
switch ($x) {
default:
throw new Exception('bad thing happened');
}
} catch (Exception $z) {
}
?>
Expected result:
----------------
Nothing
Actual result:
--------------
With --enable-debug:
/usr/local/src/php5/php-5.0CVS/php-src/Zend/zend_execute.c(675) : Freeing
