From 90c964fb069bfa9934493481f8ccfefef9c3b3fe Mon Sep 17 00:00:00 2001 From: weili Date: Fri, 22 Apr 2016 15:25:14 -0700 Subject: Add a simple check for V4 cross reference table Some unknown software generates cross reference table with the claimed object numbers are all off by one. Add a simple verification function to detect this scenario, thus have a chance to rebuild the correct cross reference table. To avoid unnecessary checks and potiential performance hit, we only check for the very first non free entry.
