Hi,

I migrated website running on Apache 1.3.33 (built from sources) from Fedora
Core 3 32bit -> 64bit and site is malfunctioning now. 
I use these per-directory mod_rewrite rules:

RewriteEngine On
RewriteCond %{HTTP_HOST} web\.(com|net)
RewriteRule ^$ client/%1/index.php [L]

RewriteCond %{HTTP_HOST} web\.(com|net)
RewriteRule ^x(.*) client/%1/$1

RewriteRule ^client/(com|net)/LX-([^-/]+)/*$ client/$1/lx.php?x=$2

...

After query for homepage, '[Wed Jun  1 10:33:50 2005] [notice] child pid 8816
exit signal Segmentation fault (11)' appends to error log file. 

Without 2nd and 3rd rule everything is ok.

Using 64bit processors (dual Opteron) on 32bit OS works fine.
