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.
