From 86f660b1f1dc207897281a77f969a56b2e551374 Mon Sep 17 00:00:00 2001 From: Andre Noll Date: Wed, 21 Jun 2006 04:46:05 +0200 Subject: [PATCH] object-refs: avoid division by zero Currently, we don't check refs_hash_size size and happily call lookup_object_refs() even if refs_hash_size is zero which leads to a division by zero in hash_obj().
