Sorry, this is a bug in e2fsck; we should handle this kind of
corrupted inode better.

The quick workaround is this:

debugfs -w -R "clri <14109880>" /dev/vg/root 

This will zap the contents of the offending inode, since it's been
overwritten with garbage; unfortunately, it was garbage which was
causing e2fsck to try to allocate too much memory, and then fail.
