Description:
------------
I'm running FreeBSD 5.4-STABLE with PHP 5.05 (I can also reproduce 
this with the same version on 7-CURRENT) and something in the soap 
module is causing php/apache to crash.
I'm using the soap module to connect to MapPoint to retrieve location 
coordinates.  This problem doesn't happen with the 5.04 soap module.  
Thanks for any help or suggestions.  Let me know if I need to provide 
any more debug information.

Reproduce code:
---------------
http://am-productions.biz/soap-crash-code.txt

Expected result:
----------------
The latitude and longitude will be displayed.  2 floating point numbers.

Actual result:
--------------
I've also tried without xdebug and I get the same problem.

The backtrace follows:

When I compile with debug it don't crash, but I get the following from valgrind:
