Description:
------------
When creating a new SoapClient PHP will segfault if the client is 
unreachable or returns a 404. This behavior appears to be "fixed" if 
date.timezone is defined in php.ini or if error_log is not set 
(regardless of whether log_errors is on or off).

Reproduce code:
---------------
try
{
    $client = new SoapClient("http://1.2.3.4/wsdl");
}
catch(Exception $e)
{
    echo "\n\nNO SEG FAULT!\n\n";
}

Expected result:
----------------
See 'NO SEG FAULT' printed to screen

Actual result:
--------------
Segmentation fault

Same behavior with php5.2-201002021330 from 
http://snaps.php.net/php5.2-latest.tar.gz

I tried to paste in the back trace but I get "Please do not SPAM our bug 
system."
 [2010-02-03 00:42 UTC] derick@php.net 
Please put it on pastebin.com and provide a link then.
 [2010-02-03 21:31 UTC] william at therileys dot freetcp dot com 
It is essentially the same back trace. Full content here: http://pastebin.com/f47226472
 [2010-02-03 22:00 UTC] jani@php.net 
That was not the backtrace of the build with the snapshot. Please, provide the correct backtrace.
 [2010-02-03 22:23 UTC] william at therileys dot freetcp dot com 
I did another back trace just to verify the correct php version was 
being used and with the source code in place on the system on which I 
ran gdb.

Please note that the back trace will say 5.2.12 (even though this is the 
snapshot) because I used that directory name so I did not have to 
rewrite the spec file to build an RPM.

The shortest way to reproduce:

# php -n -dlog_errors=on -derror_log=./foo \
 -r 'new SoapClient("http://localhost/wsdl");
 [2010-02-03 23:19 UTC] jani@php.net 
This is bug in SOAP extension which has a funky error handler defined.

Description:
------------
In case there is some problem with extension loaded from php.ini (shared 
dependency not available), php segfaults while trying to show error.

it happens in debug+zts mode at least.
