------- Comment #2 from pinskia at gcc dot gnu dot org  2006-03-19 06:00 -------
The expression which is causing the ICE is a PLACEHOLDER expression:
(gdb) p debug_generic_expr (*expr_p)
<PLACEHOLDER_EXPR struct test_246384__t2D.1107>

Author: ebotcazou
Date: Fri Sep 15 18:32:24 2006
New Revision: 116981

        * decl.c (same_discriminant_p): New static function.
        (gnat_to_gnu_entity) <E_Record_Type>: When there is a parent
        subtype and we have discriminants, fix up the COMPONENT_REFs
        for the discriminants to make them reference the corresponding
        fields of the parent subtype after it has been built.
