Although this information doesn't seem to have become more usable, so it 
could be that I'm doing something wrong here.

I'm running this on a Intel Q6600 (4 cores) and am currently using an 
i686 kernel (2.6.18-6-686-bigmem).

ii  php5                         5.2.6.dfsg.1-1+lenny3 
server-side, HTML-embedded scripting language (metapackage)
ii  php5-mysql                   5.2.6.dfsg.1-1+lenny3        MySQL 
module for php5

Although disabling the module for the cli (by removing the 
/etc/php5/cli/conf.d/mysql.ini) seems to have no effect, it still crashes.
