        * ipa-icf.c (sem_item_optimizer::traverse_congruence_split):
-       Replace ctor with auto_vec and initialization in a loop.
+       Replace array initialization (using a variable post-increment)
+       that possible triggers multiple unsequenced modifications
+       with a pair of pushes to a vector.
