Started with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=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:
5880 case 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)))
5884 return 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.
