Fix:
Index: gcc/tree-vect-loop-manip.c
===================================================================
--- gcc/tree-vect-loop-manip.c (revision 196167)
+++ gcc/tree-vect-loop-manip.c (working copy)
@@ -187,6 +187,7 @@ adjust_debug_stmts (tree from, tree to,

default defs are dominating all uses, so in adjust_debug_stmts_now we
wouldn't do anything for them. Thus, just ignore them.
