So you're saying that with PHP 4.2.0RC1 it works?

Configuration:
./configure --with-apxs --enable-debug
php.ini = php.ini-recommended
Apache 1.3.12
I have been using a procedure to create nicely-formatted tables of
arrays and their contents for a long time. It works very well under
4.1.2 (and previous 4.* verions) for displaying $GLOBALS if
session_start has not been called. If session_start has been called,
it causes a seg-fault when the $HTTP_SESSION_VARS and/or $_SESSION is
processed.
My normal script is much more elaborate, but I've stripped it to the
bare minimum to make the bugs more obvious. There are four 'fix'
comments in the code - implementing any one will make the problem go
away, but none should be necessary.
I have compiled 4.2.0rc1 with the same ./configure options and used the
4.2.0rc1-supplied php.ini-recommended file as part of a further test.
The output is the same, but the seg-fault is not reported to the error
log with 4.2.0rc1.
------------ index.php -------------------
<?PHP
# fix 1 is to pass the array by value
function CVTT (&$array, $depth=0) {
if($depth==0) {
print "<PRE>\n";
}
while(list($key,$value)=each($array)) {
# fix 2 is to skip both instances of the session variables array
### If this session-skipping block is enabled, there are no problems
# if($key=="_SESSION" || $key=="HTTP_SESSION_VARS") {
# print "skipping $key\n";
# continue;
# }
### End of session-skipping block
for($c=0;$c<$depth*5;$c++) {
print " ";
}
print "$key=";
if(is_array($value)) {
$valuestring="Array";
} elseif(is_object($value)) {
$valuestring="Object";
} elseif(is_bool($value)) {
if($value) {
$valuestring="Boolean True";
} else {
$valuestring="Boolean False";
}
} else {
$valuestring=$value;
}
print "$valuestring\n";
if(is_array($array[$key])) {
# fix 3 is to pass $value instead of $array[$key]
CVTT($array[$key], $depth+1);
}
}
if($depth==0) {
print "</PRE>\n";
}
}
# fix 4 is to eliminate the session_start
session_start();
$_SESSION['one']="two";
?>
<HTML>
<HEAD>
</HEAD>
<BODY>
<?PHP
CVTT($GLOBALS)
?>
</BODY>
</HTML>
---------------end of index.php -------------
I was not able to get a backtrace by following the instructions in the
php documentation. I'd be happy to try again with more-detailed
instructions.
If there is any further testing you would like, please let me know.
Sincerely,
Bryan
