I am busy trying a cross-compile of gdb and will see if I can get it to
run and produce the backtrace for you.

Well, I don't have an ARM system either.
So I really doubt we can fix something we can't reproduce and there is
no backtrace.

I cannot generate a backtrace as I do not have gdb on the embedded ARM
system. I have also been unable to reproduce the problem on a system
where I have gdb.
I have been able to islolate the problem to this line of code.
while (list($key,$value) = each($result)){
I have checked and $result is a valid array of values.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Description:
------------
I was running 5.0.4 (cgi) on an ARM processor (embedded) with linux
2.4.27 and it worked successfully. I have now upgraded to linux 2.6.20
and PHP 5.2.1 (cgi) and I now get a segmentation fault on some of my
scripts that previously worked. I have no gdb on the embedded system
and have not been able to reproduce the problem on my SuSE linux
systems.
Reproduce code:
---------------
Part of code ...
<table>
<?php
exec("/usr/sbin/ntpq -c peers",$result);
while (list($key,$value) = each($result)){
$table = split(" *",trim($value));
if ($key == 0){
echo "<tr>";
echo "<th>Reference</th>";
echo "<th>$table[0]</th>";
echo "<th>$table[1]</th>";
echo "<th>$table[2]</th>";
echo "<th>$table[3]</th>";
echo "<th>$table[4]</th>";
echo "<th>$table[5]</th>";
echo "<th>$table[6]</th>";
echo "<th>$table[7]</th>";
echo "<th>$table[8]</th>";
echo "<th>$table[9]</th>";
echo "</tr>";
Expected result:
----------------
-bash-3.2# ./php -v
PHP 5.2.1 (cgi) (built: Feb 23 2007 17:03:34)
Copyright (c) 1997-2007 The PHP Group

Expected result is a table of values.
Actual result:
--------------
Result:
-bash-3.2# ./php ../htdocs/ntp.php
