These testcases demonstrate what happens in cfgrtl.c, why is cfg_layout_merge_blocks miscompiled: ((a)->il.rtl->end_)->code is expected not to change during call to try_redirect_by_replacing_jump() Command line to demonstrate: $ gcc -O[123s] -fipa-pta pr43879.c pr43879-2.c && ./a.out Aborted -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43879
