Our server is Apache/1.3.12 (Unix) PHP/4.0.1pl2 AuthMySQL/2.20.  PHP is configured thus: './configure' '--with-apache=/usr/local/work/apache_1.3.12' '--with-mysql'

We've discovered that forms that worked with PHP 3.0.16 are now failing.  The client reports that the results document contains no data.  At the same time, Apache error log reports "child pid #### exit signal Segmentation fault (11)."  Changing the form from post to get permits it to work -- but of course produces a lot of data in the public URL that we prefer to hide.  This affects forms which do NOT query MySQL as well as ones that do query MySQL.  BUT, forms which query MySQL and use post that are not protected by mod_auth_mysql work properly.  (I am copying this info to mod_auth_mysql maintainer Zeev Suraski <bourbon@netvision.net.il>.)
