Started with http://gcc.gnu.org/viewcvs?root=gccview=revrev=171461
The patch has been backported to 4.6 branch as well and if built with
--enable-checking=yes, it ICEs there the same way.

In:
5880case COMPONENT_REF:
5881  /* If this component is really a base class reference, then the
field
5882 itself isn't definitive.  */
5883  if (DECL_FIELD_IS_BASE (TREE_OPERAND (instance, 1)))
5884return RECUR (TREE_OPERAND (instance, 0));
5885  return RECUR (TREE_OPERAND (instance, 1));

instance is a COMPONENT_REF with type Pos, TREE_OPERAND (instance, 0) is
INDIRECT_REF - *coords and TREE_OPERAND (instance, 1) is not FIELD_DECL, but
IDENTIFIER_NODE pos.
