Description:
------------
I'm using PEAR package SOAP 0.9.4, PHP 5.2.0

I keep getting apache illegal instructions when making calls to my PEAR SOAP_Server service I think is_array does some kind of infinite loop when it dives into a nested array of objects/arrays

The SOAP_Fault created by PEAR is finite in length and is not that big, I don't see why the stack is overflowing when is_array is walking the var



[nkiraly@test00 /var/www/test]$ fetch
http://test00/~nkiraly/test/pear_soap_sig4.php
fetch: http://test00/test/pear_soap_sig4.php: Unknown error: 0

[Fri Jan 05 01:27:41 2007] [notice] child pid 27266 exit signal Illegal
instruction (4)


investigation has led me to the is_array call in Base.php on line 989, in
_makeEnvelope():

            if (is_array($method)) {

I see the test is wether or not the $method var passed is an array and to
serialize each one if 
there is more then one. is_array seems to be bombing in a potentially
infinite loop kind of way.


i got fatal error at 16mb so i brought it up to 300MB and i got what looks
like a stackoverflow error,
which leads me to believe it's some kind of infinite loop with that many
iterations with the return object

Reproduce code:
---------------
code here:

http://koadweb.com/pear_soap_sig4/pear_soap_sig4.php.txt

Expected result:
----------------
the verifyMember method will be serviced and value returned, but it never
gets that far

Actual result:
--------------

that's the 16MB php memory limit

.. here's 300MB

i cut out the middle of the stack, but here is the idea of what happens:
