Description:
------------
I create Backports of the Debian Sid packages for Woody.   
There I detected the following error with the apache2  
module.  
  
Every call of a php call let apache2 (mpm-prefork) lets   
apache2 segfaulten, even sometimes if php4 is not called   
it segfaults.   
 
Another user of Debian Sid (no backports), has the same 
problem. Before monday I'm not able to provide you with a  
gdb backtrace, because I don't have my build environment  
available.  
 
But at 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=259808 
and  
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=259659 
 
are a few more informations and a backtrace.  
If somebody from Maintainers already reported that 
problem, I'm sorry for this bugreport, but this is really 
urgent. 
 

Actual result:
