For a quick check, I just tried it on
c-c++-common/asan/heap-overflow-1.c at -O0

    #0 0x11258 in main
/vol/gcc/src/hg/trunk/local/gcc/testsuite/c-c++-common/asan/heap-overflow-1.c:21

vs. -O1:

    #0 0x1121c in main
/vol/gcc/src/hg/trunk/local/gcc/testsuite/c-c++-common/asan/heap-overflow-1.c:24

-fno-delayed-branch made no difference.
