To reproduce try php from ports, make config with multibyte, then install
magento shop 1.6 and keep refreshing... :)

Confirm bug happening on php5.3.9 apache 2.2.21 Freebsd8. PHP compiled with
zend_multibyte support.
pid xxxx (httpd), uid 80: exited on signal 11
another simptom in vhost error.log : PHP Fatal error: require_once() Failed
opening required '1'
(intermittent, file exists and works 90% of the time). Browser gets white
screen of death. Refreshing the page will work ok usually.

It was tested on Apache 1.3.41 and 2.2.19.
I will try on another server later.

I can not reproduce this in my environ, and your apache seems to be ancient
version, could you test with a newer version of it? thanks
