On my debian/ 4.3.2-dev it doesn't segfault. Valgring reports memoery
read errors. Here is the script modified :
<?php
$a['one']['two']['three']['four'][] = array("FILE_NUMBER"=>2256,
"INGEST_DATE"=>'2003-01-16');
$a['one']['two']['three']['four'][] = array("FILE_NUMBER"=>2258,
"INGEST_DATE"=>'2003-01-17');
$num = nodeCount($a);
print $num;
function checkNode($v, $var) {
var_dump($v, $var);
echo str_repeat("-=",30)."\n";
if (is_scalar($var)) {
$v += 1;
} elseif (is_null($var)) {
} else {
echo "Recursy down\n";
$v += nodeCount($var);
//$v = 2;
echo "Recursy up\n";
}
echo "checkNode - END\n";
return $v;
}
function nodeCount($array) {
$number = 0;
if (is_array($array)) {
$number = array_reduce($array, "checkNode" , 0);
}
return $number;
}
?>
checkNode calls recursively itself. After getting of the recursy
something bad happens at this line :
zend_hash_move_forward_ex(Z_ARRVAL_PP(input), &pos);
I think this is the line.
Unfortunately I cannot help more atm.

It core dumps when I run it from the command line.
% gdb /usr/bin/php core.30270
[symbols blah blah]

Using array_reduce on a nested list causes a segfault.
The following code isolates the problem.
<?php
$a['ANY']['F550M']['HRC']['j6jt01dlq_flt.fits'][] =
array("FILE_NUMBER"=>2256,
"INGEST_DATE"=>'2003-01-16');
$a['ANY']['F550M']['HRC']['j6jt01dll_flt.fits'][] =
array("FILE_NUMBER"=>2258,
"INGEST_DATE"=>'2003-01-17');
$num = nodeCount($a);
print $num;
function checkNode($v,$var) {
print "<pre>";
print_r($var);
print "</pre>";
if (is_scalar($var)) {
$v += 1;
}
elseif (is_null($var)) {
}
else {
$v += nodeCount($var);
}
return $v;
}
function nodeCount($array) {
$number = 0;
if (is_array($array))
$number = array_reduce($array,"checkNode",0);
return $number;
}
?>
How reproducible:
Always
Steps to Reproduce:
1. Execute code snippet
Actual Results: apache error_log:
[Fri Feb 21 12:52:52 2003] [notice] child pid 5618 exit signal
Segmentation
fault (11)
Expected Results: This code should count the scalar nodes in the
nested list.
It should print the number 4.
