I can't reproduce this. Where in your apache.conf do you have that

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 =)
