Hmm... 

 The script that i can get to segfault if i put some other code (nothing to do
with phpsoap) will stop segfaulting too. 

 The thing im curious about is im not able to get the hello_world example to
crash. try pulling down the current cvs. run the script again, the one that
crashes, tail logs/error_log see if thers a segfault in there.
