>Description:
Starting apache22 with no changes to httpd.conf, it will crash immediately in bn_mul_add_words. If you comment out the "LoadModule ssl_module", then apache22 starts up.
This is for apache-2.2.0_5 with openssl-0.9.8a.
mail# /usr/local/etc/rc.d/apache22.sh start
Performing sanity check on apache22 configuration:
Syntax OK
Starting apache22.
