zztest.cpp: In function `void foo()':
zztest.cpp:9: error: Invalid operand to binary operator
(struct N *)i.6;
zztest.cpp:9: internal compiler error: verify_stmts failed.
class N {
public:
N() {}
};
N x(N, N) {return N();}
void foo()
{
N b,c;
static N a[2]; // no ICE without static
for (unsigned i=1; i < 2; ++i)
a[i] = x(a[i-1], b);
}
Reading specs from /usr/local/lib/gcc/i686-pc-cygwin/3.5-tree-ssa/specs
Configured with: ./configure --enable-languages=c,c++ : (reconfigured)
./configure --enable-language
s=c,c++ : (reconfigured) ./configure --enable-languages=c,c++
Thread model: single
gcc version 3.5-tree-ssa 20040307 (merged 20040305)
The code worked with GCC 3.5.0 (some days ago).

"Lowering" strikes:
From:
i.6 = (struct N *)i;
T.7 = i.6 + &a - 1B;
To:
T.7 = (struct N *)i.6 + (struct N *)&a - 1B;
But then again C++ is producing werid trees (i.e. if I disable some lowering from happening in the
front-end, this works as expected).

After disabling the lowering I get:
T.5 = i - 1;
<D1486> = a[T.5];
