+Subject: [PATCH] Fix memory leak parsing group address.
+
+When there was a group address terminator with no previous addresses,
+an address would be allocated but not attached to the address list.
+
+Change this to only allocate when last exists.
+
+It would be more correct to not allocate at all unless we are inside a
+group list, but I will address that in a separate commit to master.
