I will attach a small reproducer.
/* Reproducer for optimizer bug in gcc svn trunk revision 114570
(as checked out 2006_06_12_0834 PDT)
To produce correct output:
g++ -Wall -O0 gcc_trunk_2006_06_12_0834_fc5_x86_64.cpp
./a.out
To see the bug:
g++ -Wall -O1 gcc_trunk_2006_06_12_0834_fc5_x86_64.cpp
./a.out
Note the difference in the last line of the output:
Correct: 1 0 0
Incorrect: 0 0 0
The output is also incorrect for -O2 and -O3.
The last line of the output is correct if compiled with:
g++ -Wall -O1 -DBAD_WORKAROUND gcc_trunk_2006_06_12_0834_fc5_x86_64.cpp
./a.out

------- Comment #2 from pinskia at gcc dot gnu dot org 2006-06-13 04:41 -------
Hmm, we get after dce, just:
reduced_cell_two_folds[26] = {};
And DCE removes:
this_616 = &reduced_cell_two_folds[26].u;
....
# SMT.68_1055 = V_MAY_DEF <SMT.68_1054>;
this_616->elems[0] = 1;
# SMT.68_1056 = V_MAY_DEF <SMT.68_1055>;
this_616->elems[1] = 0;
# SMT.68_1057 = V_MAY_DEF <SMT.68_1056>;
this_616->elems[2] = 0;
...
this_621 = &reduced_cell_two_folds[26].h;
...
# SMT.68_1058 = V_MAY_DEF <SMT.68_1057>;
this_621->elems[0] = 2;
# SMT.68_1059 = V_MAY_DEF <SMT.68_1058>;
this_621->elems[1] = 1;
# SMT.68_1060 = V_MAY_DEF <SMT.68_1059>;
this_621->elems[2] = 1;
Which does not make sense. Nothing is special in alias shows what is going
wrong.

Confirmed.
Shorter testcase (should return 0, but returns 1):
====================================================================
struct A
{
int i, j[9];
A() : i(1) { j[0]=j[1]=j[2]=j[3]=j[4]=j[5]=j[6]=j[7]=j[8]=0; }
};
struct B
{
A a;
};
B b[] =

{}, {}, {}, {}, {}, {}, {}, {}, {}, {},
{}, {}, {}, {}, {}, {}, {}, {}, {}, {},
{}, {}, {}, {}, {}
};
int main()
{
return 1 - b[sizeof(b)/sizeof(B) - 1].a.i;
}

The only thing i can think of is that SMT.68 is not marked global.
Is it?

Some how I missed that before:
SMT.68, UID 2839, struct reduced_cell_two_fold_info, is aliased, is addressable

So it should have been marked global, and should alias the global var, but
apparently the global var doesn't pop into it's alias set

No, because this one is still present.
(Or the fix in PR 28410 is incomplete.)

This is impressive.
We add b as a may alias to the SMT, then it disappears from the list before
call clobbering!
