The attached code triggers an ICE when compiled with -O3:
internal compiler error: in loop_optimizer_init, at loop-init.c:46
-O2 works. This was first encountered in revision 137631. The test case is
already reduced from a much larger program, but still has 1000+ lines. I was
not able to reduce it further.
