--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Hmm.

Replaced g8 with 0B in all uses of g8.1_2 = g8;
Applying pattern match.pd:277, gimple-match-10.cc:11622
gimple_simplified to _3 = (long int) g11.0_1;
Replaced g19 with g19.2_4 in all uses of g19.3_5 = g19;
Applying pattern match.pd:5859, gimple-match-6.cc:8731
Inserted _13 = (void *) (void *) g11.0_1;
Replaced MEM[(void * *)g19.3_5] with _13 in all uses of _6 = MEM[(void *
*)g19.3_5];
