Here is exactly what I did to reproduce the problem.  This is on an AIX 4.3.3 box with Oracle 9iAS which runs Apache 1.3.12.  I have successfully installed PHP on Oracle 8iAS which runs Apache 1.3.9.

Here's the exact steps I took to install PHP:

NOTE: I ran all of this as the oracle user and I had my ORACLE_HOME set to /ias/6iserver.  This shouldn't be necessary since we specify this on the configure line but I did it to be safe.

Added -I/ias/Apache/perl/lib/5.00503 to the end of the #!perl call at the top of the apxs script.  A perl module (strict.pm) is required but is not found in the include path when the configure script runs apxs.

Also, I'm not sure why, but Oracle 9iAS automatically assumes everyone is running Solaris.  In the apxs script I  changed a '-DSOLARIS2=260' reference to -DAIX=43.

Ran CC=cc configure --with-apxs=/ias/Apache/Apache/bin/apxs --with-oci8=/ias/6iserver --without-mysql --prefix=/ias/Apache/Apache

After the configure script was done I edited config_vars.mk and added -I/ias/rdbms/demo and -I/ias/rdbms/public to the INCLUDES variable.  IAS keeps some of the oci8 header files in these directories.  Also, for 9i I had to add -I/ias/Apache/Apache/include to the INCLUDES variable.  I did not have to do this for 8iAS.

AIX has a sparsely documented bug where alloca() is not defined on the system and the PHP configure script does not seem to handle this properly.  We need to add -ma to CFLAGS to get around this.

Created a link in /ias/6iserver/lib for libclntsh.a.  For some reason only a .so was included in 9iAS.  I checked 8iAS and this file is not missing here.  Ran ln -s libclntsh.so libclntsh.a in the /ias/6iserver/lib directory.

Ran make.

Ran make install.

Apache starts up ok, but I get a seg fault at the first call to PHP.  Only the child http process dies.

Apache error log shows:

Any ideas?
