+Subject: [PATCH] btrfs-progs: corrupt-block: fix memory leak in debug_corrupt_sector().
+
+ASAN build (make D=asan) detects a  memory leak in
+btrfs-corrupt-block inside debug_corrupt_sector().
+
+This can be reproduced by fsck/013 test case.
+
+The cause is pretty simple, we just malloc a sector and forgot to free
+it.
+
+Issue: #806
