[Bug tree-optimization/33458] New: [4.3 regression] ICE "PHI def is not a GIMPLE value"

[reichelt at gcc dot gnu dot org]

The following valid testcase triggers an ICE on mainline
when compiled with "-O":

===================================
inline void foo(int* p, int n)
{
  for (; n > 0; --n, ++p)
    *p = 0;
}

struct A
{
  int x[2];
  A() { foo(x, 2); }
};

inline A getA() { return A(); }

struct B
{
  A a;
  B();
};

B::B() : a(getA()) {}
===================================

bug.cc: In constructor 'B::B()':
bug.cc:20: error: PHI def is not a GIMPLE value
p_2 = PHI <&this_1(D)->a.x[0](2), p_5(3)>

&this_1(D)->a.x[0];

bug.cc:20: internal compiler error: verify_stmts failed
Please submit a full bug report, [etc.]

The regression was introduced between 2007-06-23 an 2007-07-02.
