I think the problem has been found, but it might be difficult to fix.
Look at the Bugzilla discussion in the Fedora mailing list:
Apparently the glibc folks implemented a new version of the glibc
routine that does memory-copies fin Fedora 14. And unlike the old
version, this one corrupts data when copying between memory areas
Stricly speaking, doing that is not valid. But it is apparently
quite common - the Bugzilla entry lists quite a few apps that
break because of this change - and it has worked until the change
in glibc. So the glibc maintainers is taking the "not a bug - won't fix"
In which case the problem has to be fixed in all of the applications
and libraries that do the invalid memcpy, i.e. the rrdtool library
in this case.
