Operating system: SCO OpenServer 5.0.6
PHP version:      4.3.2RC3
PHP Bug Type:     Reproducible crash
Bug description:  PHP crashes with segfault as soon as it is loaded

Compilation attempted on SCO OpenServer 5.0.6 with the following configure
line:

./configure --prefix=/usr/local/php-4.3.1 --disable-all --enable-sysvsem
--enable-sysvshm --enable-debug

The compilation appears to successfully complete and 
Installation takes an age, this seems to be down to the php program in
/sapi/cli segfaulting.  Any attempt to use any of the compiled 'php'
programs also results in a segfault. Once installed the same problem
occurs. Following is a back trace using gdb.

    bash-2.03# ./php
    Segmentation Fault (core dumped)
    bash-2.03# pwd
    /usr/local/php-4.3.2RC3/bin

This system has successfully compiled, and is running, 4.2.3 and I've not
experienced any problems compiling up previous versions (4.1.X).

I was planning on skipping 4.3.1, but after 4.3.2RC3 failed I tried it and
got a similar problem with it. I've attached the backtrace for it just in
case.
