The problem occurs when a package uses a library which has a DT_NEEDED reference to an older libc library, but the snapshot has moved to a new library major/minor version. Then ld.so loads both libraries, and that won't work. This DT_NEEDED stuff is very much designed to discourage any trend other than ossification.
