New Comment:
Too bad... on my system (and the systems of two friends) we could
reproduce this bug.
Maybe we will find out more about the circumstances, when we try to
reproduce it during our lecture (starting end of april).
Until then I will not be able to provide any new feedback.

Works fine on windows, linux 32/64bit for me.

I don't think to use any. I am using PHP on an apache-webserver, if
that makes a difference.
Could also not reproduce this on linux with Version 5.2.6, had no
higher versions on a linux system to test it. Will try that later.

I can't reproduce this on Linux or OS X
Do you have any Zend Extensions enabled such as eAccelerator, APC, Zend
Optimizer or anything like that?

Except from the "<?php" and "?>" I already posted the shorter script.
<?php
function test() {
$array = array("test");
foreach($array as $element) {
for($j=0;$j<5;$j++) {
continue 2;
}
//inserting code here affects return-value
return true;
}
return false;
}
echo test()?"true":"false";
?>

Description:
------------
The echo ""; affects the "return true;" below.
As long as the echo is there everything works as expected, if you put
"//" in front of the echo, the return will be called even if it should
not.
Reproduce code:
---------------
function matchHostList($host, $list_file) {
$host = explode(".", $host);
//$list_contents = explode("\n", file_get_contents($list_file));
$list_contents = array("www.google.de");
foreach($list_contents as $list_host) {
$list_host = explode(".", rtrim($list_host));
//if the list-host is more specific than the tested host we
can't
match
if(count($host) < count($list_host))
continue;
for($i = 1;$i<=count($list_host) && $i <= count($host);$i++) {
if($list_host[count($list_host)-$i] !=
$host[count($host)-$i])
continue 2;
}
echo ""; //this is necessary to avoid wrong return
return true;
}
return false;
}
echo matchHostList("false.google.de", "")?"true":"false";
Expected result:
----------------
When running as shown above this returns false (because "continue 2;"
continues the loop above the "return true;"), this is OK.
If you remove the echo ""; above the "return true;" You would expect
that nothing changes (because we only removed some null-output), but in
fact the return value changes to true.
Actual result:
--------------
see Expected result
