[CentOS] Aide error "Caught SIGBUS/SEGV"

One of my servers has recently started giving an error every time I run "aide --check". I ran it manually twice today with the same results. The second time, I added the -V flag, but that didn't give me anything useful. The system is currently running CentOS 5.3.

Nothing on the system has changed recently (that I am aware of). The Aide database hasn't been updated in a few months.

This is the error I am seeing:

Caught SIGBUS/SEGV while mmapping. File was truncated while aide was running? Caught SIGBUS/SEGV. Exiting

I tried Googling for it, but didn't find anything helpful.

Any ideas?
