Have Apache 2.0.52-r1, PHP 4.3.10, and mod_php installed. PHP took a lot of effort to install; ended up compiling it using these USE flags: dba gd mysql -cpdflib Problem: PHP4 gives a segmentation fault. Ordinarily I would not post a bug report for something like this when PHP5 is on the way, but PHP4 is _very_ widely used and this is a serious bug (possible configuration problem?). bash-2.05b$ cat /var/log/apache2/error_log ...
