Nice. Now it's really an aliasing problem only - and maybe bad timing for when
we end up with such nice state.

We now get:
dX.D.2296.D.2252.domain_m[0].D.2209.D.2200.D.2154.domain_m = 1;
dX.D.2296.D.2252.domain_m[1].D.2209.D.2200.D.2154.domain_m = 0;
k.D.2296.D.2252.domain_m[0].D.2209.D.2200.D.2154.domain_m = 0

Bug 19626 depends on bug 17141, which changed state.

Most of the problem is PR 17141, the other problem comes into play with struct
aliasing issues.

Revised testcase without confusing casts
This changes the testcase to not cast int* to Loc<1>*, but use

Actually, exchanging loc_test for
int loc_test(void)
{
const Loc<2> k(0, 1);
return k[0].first();
}
shows the same problem:
:
D.2541 = (struct Loc<1> *) &k.D.2190.D.2155.domain_m.buffer;

D.2540 = (struct Loc<1> *) &dX.D.2210.D.2166.domain_m.buffer;
That confuses the aliasing mechanism
buffer is of type int* but you are casting it to Loc<1> *.

If you had used the correct types in the first place instead of this crazy
uninitialized pointer this works
(almost):
dX.D.2220.D.2170.domain_m.buffer[0].D.2098.D.2055.domain_m = 1;
dX.D.2220.D.2170.do
