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.


------------------------------------------------------------------------

[2007-02-27 12:45:00] errol at issi dot co dot za

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.

------------------------------------------------------------------------

[2007-02-27 12:31:20] tony2001@php.net

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
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies

Expected result is a table of values.

Actual result:
--------------
Result:
-bash-3.2# ./php ../htdocs/ntp.php

The backtrace isn't really useful, the most important information is
missing - on which line the crash happens.
Make sure PHP is compiled with --enable-debug.

The backtrace isn't really useful, the most important information is
missing - on which line the crash happens.
Make sure PHP is compiled with --enable-debug.

I managed to get gdb to cross-compile and run on the ARM. Here is the
backtrace

Default #40658 : Segmentation fault

Updated by: tony2001@php.net

Bug Type: CGI related
Operating System: Linux 2.6.20 on ARM
PHP Version: 5.2.1
New Comment:


Again, we would like to know where exactly it happens, not just the
function name.
Try to compile it with CFAGS="-O0 -g" and regenerate the backtrace.
Btw, is there valgrind for Linux on ARM? It would help very much.

It does not look like valgrind runs on ARM.

That's bad.
The other request still applies, though.
