From 428556cd130db0cfcffd6fe081f32dc1218a904f Mon Sep 17 00:00:00 2001 From: Jared Camins-Esakov Date: Wed, 2 Feb 2011 11:47:49 -0500 Subject: [PATCH] Bug 5683 - it is possible to save corrupt records This patch makes it impossible to save records with variables fields that don't contain any subfields. Prior to this patch, link_bibs_to_authorities.pl would sometimes corrupt records.
