Its really strange, because i have several php53 installations without

any trouble with the same configuration, but only on one dev server it

crashes. if you cannot reproduce, its not a big deal that you can get 
access to our dev server, there are not secrets and no data...

I can't reproduce this.  Where in your apache.conf do you have that
line?  As in which config blocks is it inside?

Description:
------------
Segmentation fault if the following line is enabled in apache.conf:

php_admin_value open_basedir 
/www/htdocs/ecolint.ch/dev:/www/htdocs/ecolint.ch/tmp:/www/htdocs/ecol
int.ch/mysql

Maybe i made something wrong or its not a bug in php, because i not 
really understand the debug output, but i hope it helps =)
