Description: PHP seg faults in alloca() at first PHP request to Apache

I see this snippet in my config.log where it's not finding alloca.h.  I did not find 
alloca.h in the PHP source tree or anywhere on my system.

configure:5777: checking for alloca.h
configure:5787: cc -E  -DAIX=43 -DMOD_SSL=204110 -DEAPI -DUSE_EXPAT conftest.c 
>/dev/null 2>conftest.out
"configure", line 5783.10: 1506-296 (S) #include file <alloca.h> not found.
configure: failed program was:
#line 5782 "configure"
#include "confdefs.h"
#include <alloca.h>
configure:5777: checking for arpa/inet.h
configure:5787: cc -E  -DAIX=43 -DMOD_SSL=204110 -DEAPI -DUSE_EXPAT conftest.c 
>/dev/null 2>conftest.out
configure:5777: checking for crypt.h

Do you guys have any ideas what this is?  I can keep trying different things on this 
but I don't have a direction.  We are desperate to run PHP.  I did try installing to 
our actual Apache directory instead of soft linking /usr/local and we came up with the 
same thing.

We are running Oracle IAS on AIX 4.3.3.  Oracle's IAS runs Apache 1.3.9 and 
the root Apache directory is in /ias/Apache/Apache.  We have a soft link from 
/usr/local/apache -> /ias/Apache.  We are installing our PHP source from 
/usr/tools/src/php-4.0.4pl1/ and I believe the config script uses /usr/local as it's 
prefix?  We ran make and make install and we bring up Apache with mod_php 
successfully.  At the first request however, php cores in the /ias/Apache/Apache 
directory.  The request is simply running phpinfo().  I see the following message in 
our httpds_error_log:

Here's what I see in the core file:

Our configure scripts is run with:
configure --with-apxs=/ias/Apache/Apache/bin/apxs --with-oci8=/ias/6iserver 

We also made the modification to libtool in bug 4360 and tried again but we get the 
same as above.
