(ubuntu hardy) php5 and php4 both together - cli ok - apache2 segfaults..

Hi.

I have just compiled the latest php4 on an ubuntu Plesk hardy server.

It already had the distro's version of PHP - (PHP 5.2.4-2ubuntu5.4 with
Suhosin-Patch 0.9.6.2), I installed PHP4 from source.

The idea being so that if apache calls a .php5 page it gets parsed by php5 -
normal .php pages to go to php4.

It compiles fine and can run both from command line.

Also I can run either of them fine - i,e php4 OR php5 - however as soon as I
load BOTH modules (i.e no extra configuration) I get a segfault.

i.e loading any ONE php module is fine........

cli output:-

php5 :
 php -v

I get this in apache's error log

I complied php4 with

--with-config-file-path=/etc/php4
--with-config-file-scan-dir=/etc/php4/php.d --with-pic --with-pear

--with-exec-dir=/usr/lib/php4/libexec --with-iconv --enable-wddx
--enable-dbx

I load the modules with

LoadModule php4_module /usr/lib/apache2/modules/libphp4.so
LoadModule php5_module /usr/lib/apache2/modules/libphp5.so


Has anyone got any ideas how to stop apache segfaulting - i.e is it simply
some config or do i need to recompile ? As previously mentioned php4 and
php5 work 100% o.k seperately
