Yup, and it certainly affects at least apt-rpm in current Fedora 5 & 6 
kernels. I've seen a bunch of crash reports (and managed to reproduce it a 
few times myself) which all are caused by zeroes in apt's cachefile where 
data is expected...

In the cases I managed to reproduce it, no rpmdb corruption was present, 
just apt's own cachefile. But as rpm uses mmap it's at least *possible* 
some of the rpm issues people see in FC6 are caused by it.
