[php-maint] Bug#528053: php5-cli: Occasionaly crashes with 'Segmentation fault' after execution is finished

[Bas Verhoeven]

Package: php5-cli
Version: 5.2.6.dfsg.1-1+lenny2
Severity: important


The php5 cli occasionaly crashes with a 'Segmentation fault' after it is done
executing a simple PHP file.

With sample file 'test.php': <? echo 'hello' . "\n" ?>

soczol at nameless:~$ php5 test.php
hello
soczol at nameless:~$ php5 test.php
hello
soczol at nameless:~$ php5 test.php
hello
Segmentation fault

This also occurs when not parsing a .php file but just running 'php -v':

soczol at nameless:~$ php -v

Segmentation fault (core dumped)

The generated core file looks pretty useless (mainly because i'm missing the debug
symbols):

(gdb) bt
#0  0xb6f5ee90 in ?? ()
#1  0xb7818f3b in start_thread () from /lib/libpthread.so.0
#2  0xb7a49bee in clone () from /lib/libc.so.6

I can't reproduce these issues on other systems running the same php version but I
can reproduce this problem on this system.
