--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> 2013-03-18 08:26:32 UTC ---
Reduced testcase (-O3):
struct A { _Complex double a; };
struct B { A *b; void foo (void *); };
A
operator / (A x, A y)
{
A r;
r.a = x.a / y.a;
return r;
}
void
B::foo (void *x)
{
if (__real__ b[0].a)
b[0] = (static_cast <B *>(x))->b[0] / b[0];
else
b[0] = (static_cast <B *>(x))->b[0];
}
The ICE is actually
pr56635.C: In member function ‘void B::foo(void*)’:
pr56635.C:13:1: error: invalid PHI argument
B::foo (void *x)
^
MEM[(const struct A &)_9]
pr56635.C:13:1: error: incompatible types in PHI argument 1
complex double
const struct A
cstore_10 = PHI <_11(3), MEM[(const struct A &)_9](4)>
pr56635.C:13:1: internal compiler error: verify_gimple failed
and looks like cselim bug.
Started with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=186501 but guess
it just has been latent before that.

Even more reduced (-O3):
struct A { _Complex double a; };
void
foo (A **x, A **y)
{
A r;
if (__real__ x[0]->a)
{
r.a = y[0]->a / x[0]->a;
**x = r;
}
else
**x = **y;
}
