[Bug tree-optimization/17483] New: [4.0 regression] ICE at -O3 when passing a reference.

["reichelt at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compiling the following valid code snippet (inspired by PR6189)
on mainline with -O3 yields an ICE:

===================================
struct A
{
    int i;
    int& ref() { return i; }
};

A foo()
{
    A a;
    a.ref()=0;
    return a;
}

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


bug.cc: In function `void bar()':
bug.cc:15: error: address taken, but ADDRESSABLE bit not set
D.1590

bug.cc:15: internal compiler error: verify_stmts failed.
Please submit a full bug report, [etc.]

The regression was introduced 2004-09-13 or 2004-09-14.
