+Subject: [PATCH 1/1] Bug 703366: Fix double free of object during
+ linearization.
+
+This appears to happen because we parse an illegal object from
+a broken file and assign it to object 0, which is defined to
+be free.
+
+Here, we fix the parsing code so this can't happen.

+Subject: [PATCH] Bug 701297: Harden populate_ui against unexpected repairs.
+
+We count the number of layers, and allocate space for them in
+an array. We then walk the tree reading details of those layers
+in. If we hit a problem that causes a repair while reading the
+information, the number of layers can magically increase. In
+the existing code we run off the end of the array.
+
+In the new code we watch for hitting the end of the array and
+realloc as required.
