Me again, here is a last test script that work without changing
opcache.optimization_level :
APC BUG
<
// This should echo "tutu" string: >tutu<
function table_valeur($table, $cle, $defaut='') {
foreach (explode('/', $cle) as $k) {
$table = is_string($table) ? @unserialize($table) : $table;
if (is_object($table)) {
$table = (($k !== "") and isset($table->$k)) ? $table->$k :
$defaut;
} elseif (is_array($table)) {
$table = isset($table[$k]) ? $table[$k] : $defaut;
} else {
$table = $defaut;
}
}
return $table;
}
function vide($texte){
return "";
}
echo "This should echo empty string:
>".vide($Pile['vars'][$zzz=(string)'toto'] = 'tutu')."<";
echo "This should echo \"tutu\" string:
>".table_valeur($Pile['vars'],'toto')."<";
?>

Hi again Laruence,
We found that the problem comes form the cast in $Pile['vars'][(string)'toto'].
With this news test script it works as expected :
APC BUG
<
// This should echo "tutu" string: >tutu<
// Works as expected with opcache.optimization_level=0xffef in php.ini
function table_valeur($table, $cle, $defaut='') {
var_dump($table);
var_dump($cle);
var_dump($table[$cle]);
foreach (explode('/', $cle) as $k) {
$table = is_string($table) ? @unserialize($table) : $table;
if (is_object($table)) {
$table = (($k !== "") and isset($table->$k)) ? $table->$k :
$defaut;
} elseif (is_array($table)) {
$table = isset($table[$k]) ? $table[$k] : $defaut;
} else {
$table = $defaut;
}
}
return $table;
}
function vide($texte){
return "";
}
echo "This should echo empty string: >".vide($Pile['vars']['toto'] =
'tutu')."<";
echo "This should echo \"tutu\" string:
>".table_valeur($Pile['vars'],'toto')."<";
?>

Hi Laurence,
Here is a script that show the bug in action :
APC BUG
<
// This should echo "tutu" string: >tutu<
// Works as expected with opcache.optimization_level=0xffef in php.ini
function table_valeur($table, $cle, $defaut='') {
foreach (explode('/', $cle) as $k) {
$table = is_string($table) ? @unserialize($table) : $table;
if (is_object($table)) {
$table = (($k !== "") and isset($table->$k)) ? $table->$k :
$defaut;
} elseif (is_array($table)) {
$table = isset($table[$k]) ? $table[$k] : $defaut;
} else {
$table = $defaut;
}
}
return $table;
}
function vide($texte){
return "";
}
echo "This should echo empty string: >".vide($Pile['vars'][(string)'toto'] =
'tutu')."<";
echo "This should echo \"tutu\" string:
>".table_valeur($Pile['vars'],'toto')."<";
?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
hmm, are you able to get the compiled SPIP view file? it must be a PHP script
which can be used to reproduce this problem?

Typo : With opcache.optimization_level=0xffef the result is "value".
[2013-10-06 11:38:42] bruno+php at ahennezel dot info
Description:
With the SPIP CMS V3, the default optimization level
opcache.optimization_level=0x
and
opcache.optimization_level=0xffef
give different results.
Test script:
---
I dont know how to test directly in PHP, but here is a very short SPIP snippet
which brings out the problem. Put in the SPIP's sommaire.html skeleton :
#SET{var,value}
[(#GET{var})]
With opcache.optimization_level=0x the result is empty.
With opcache.optimization_level=0x the result is "value".
Expected result:
I expect the content "value"
Actual result:
--
The content is empty
