Not looking at this yet, but disabling jump threading from all passes (dom
included) makes the problem go away:
$ ./xgcc -B./ a.c -w -O2 -fno-thread-jumps && ./a.out
element 1
element 2
element 3

This seems jump threading related but I can't tell how.
-fno-tree-vrp is enough to workaround the bug but I don't have anything more
than that.
