Description:
------------
Apache 2.0.49 and PHP 4.3.6 (as well as lates CVS snapshot).

When everything is up and running I remove one of the Apache's logfiles (e.g. ~www/logs/access_log) and tell Apache to recreate it by calling "killall -HUP httpd". 

Apache immediately crashes with the following in error_log:

[Mon Apr 19 15:26:08 2004] [notice] SIGHUP received.  Attempting to restart
[Mon Apr 19 15:26:08 2004] [notice] seg fault or similar nasty error detected in the parent process

When I disable loading of the PHP module in httpd.conf everything works just fine. When I downgrade to PHP 4.3.4 it works as well.

Reproduce code:
---------------
Compile Apache 2.0.49 with 
./configure --prefix=/home/www --enable-http \
--enable-so --enable-usertrack

and PHP 4.3.6 with:
./configure --prefix=/home/www/php \
--with-apxs2=/home/www/bin/apxs

Install and run.

Make any request, remove ~www/logs/access_log and run 
'killall -HUP httpd'

Expected result:
----------------
access_log should be recreated

Actual result:
--------------
This appears in the error_log:

[Mon Apr 19 15:26:08 2004] [notice] SIGHUP received.  Attempting to restart
[Mon Apr 19 15:26:08 2004] [notice] seg fault or similar nasty error detected in the parent process
