autoreduced testcase
I am not sure if this should be marked as a regression - the code doesn't
compile in 4.7, but used to older revisions of 4.8.
Compiler output:
$ gcc -fsanitize=address testcase.c
testcase.c: In function 'foo':
testcase.c:10:1: error: gimple_bb (stmt) is set to a wrong basic block
foo (void)
^
__builtin_memcmp (&s.a, &empty, 200);
testcase.c:10:1: error: gimple_bb (stmt) is set to a wrong basic block
return;
