Description:
------------
After loading a "minimal" install of FreeBSD 5.5 on to my 
system, and updated the ports collection, I decided to load 
apache13+mod-ssl with PHP-4.4.4 and MySQL 4? (whatever shows 
as the newest version after a ports update with FREEBSD 5.5) 

Everything goes well- until after the second boot of apache. 
it totally pukes and gives a "Segmentation Fault" error.

after uninstalling and re-installing each module at a time, 
as well as changing the configuration file to exlude 
anything that I may have added- the error can not be 
reproduced unless I specify that the MySQL compatability be 
used with the installation of PHP4.

Unfortunately, I'm not one of you "L33T" guys, so my 
knowledge is limited on this matter.

I am, however, more than happy to, and completely capable of 
following instructions to get the desired information.

Reproduce code:

Also- there have been no changes to the kernel, nor any 
changes to make.conf. this occurs on a bone stock system- with 
exception to the updated "ports" files.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

You have to disable ext/recode.
Detailed explanation why ext/recode should not be enabled along with ext/mysql and ext/imap can be found here: http://php.net/recode
Not PHP problem.
