This is what "icheck -B" was for, but icheck(8) no longer exists and that particular bit of functionality does not seem to be provided in fsck(8). One current userland utility (other than fsck) which does know how to grovel through the metadata and index blocks is dump(8), but you'd have to hack on it to report which inode was using a particular block.
