[reichelt at gcc dot gnu dot org]

------- Additional Comments From reichelt at gcc dot gnu dot org  2005-07-14 20:24 -------
Confirmed. Reduced testcase (compile with -O)

=====================================
struct X
{
  int i0, i1;
  char c;
};

struct A
{
  int i;
  char c0, c1;

  virtual ~A();
};

struct B : virtual A {};

struct C : B
{
  X x;

  void bar(X y) { x = y; }
};

void foo()
{
  C().bar(X());
}
=====================================

On i686-pc-linux-gnu this results in:

PR22488.cc: In function 'void foo()':
PR22488.cc:24: internal compiler error: in first_vi_for_offset, at
tree-ssa-structalias.c:2858
Please submit a full bug report, [etc.]
