[Bug tree-optimization/20489] New: [4.1 regression] ICE: address taken, but ADDRESSABLE bit not set

[reichelt at gcc dot gnu dot org]

The following code snippet causes an ICE on mainline when compiled with g++ -O:

========================
struct A
{
    ~A();
};

struct B
{
    int i;
    A a;

    void foo() {}
};

void bar()
{
    B().foo();
}
========================

  bug.cc: In function 'void bar()':
  bug.cc:14: error: address taken, but ADDRESSABLE bit not set
  D.1597

  bug.cc:14: internal compiler error: verify_stmts failed.
  Please submit a full bug report, [etc.]
