+Subject: [PATCH] Comply with the aggressive-loop-optimization introduced in
+ gcc 4.8.
+
+The problem is in gcc loop optimizers which detect a loop operating with out of bounds memory and then optimize it with something undefined since, according to the C standard, out of bounds behavior is undefined. The problem could have been addressed by using the new option -fno-aggressive-loop-optimization as well.
