We're translating { {plus_expr,i_96,1}, {component_ref b2,b}, {component_ref
c3,array_ref i_96,c}, {plus_expr,i_29,1} } through

during partial-antic computation. And we recurse endlessly phi-translating
{plus_expr,i_96,1} already. Because the leader for i_96 we are translating

and its leader again.

Sort-of same IL with trunk if you make C c[100] global. But there's not
a single EH edge on trunk?! which likely makes it work there.

------- Comment #12 from rguenth at gcc dot gnu dot org 2010-01-27 15:35 -------
In the testcase from comment #11 on trunk when translating PA_IN [7],
{ i_45 (0028), {b2}@.MEM_46 (0007),
{component_ref<c3>,array_ref<i_45,0,4>,c}@.MEM_21 (0022), {plus_expr,i_45,1}
(0009) }
to block 20 we first translate
{component_ref<c3>,array_ref<i_45,0,4>,c}@.MEM_21
(0022) which is translated to {component_ref<c3>,array_ref<i_45,0,4>,c}@.MEM_26
(0028). Later we translate i_45 (0028) to i_45 (0028), but when entering
that into the sets the value is already present.
Thus, this particular case is fixed by value-replacing the translated
expression in phi_translate_set.
But that does not sound like a proper solution. It looks more like an
issue of sorting. Though doing the value-replacement in case of
the translation being a name looks not too weird.
Danny? Is this something that should not happen because of some
constraints which are possibly violated?
