I hit the same problem. My testcase is slightly shorter, but i'm not sure it's
also actually simpler. Requires -O -finline-functions

> cat bug.ii
struct S {
        S();
        ~S() {}
        void f();
};
void f() {
        int x, y;
        while (x) {
                x = x ? x : y;
        }
}
void g() {
        S s;
        s.f();
}
void h() {
        S s;
        f();
        g();
}

> g++ -O -finline-functions bug.ii
bug.ii: In function 'void h()':
bug.ii:16: internal compiler error: in alloc_aux_for_block, at cfg.c:665
