Hello All,
I am using sqlite-3.3.3 with yam and pysqlite on a RedHat Enterprise
Linux 4 IA64 machine. I get a lot of "unaligned access" message while
using yum.

I have noticed some warnings while compiling sqlite-3.3.3

The following confirms that the issue is coming from sqlite
python

Is this a bug in sqlite.
Thanks in advance for the help.
