dwarf2out.c (gen_typedef_die): Abort if we get identical TREE_TYPE and DECL_ORIGINAL_TYPE on a typedef.

Browse Source 
* dwarf2out.c (gen_typedef_die): Abort if we get identical
        TREE_TYPE and DECL_ORIGINAL_TYPE on a typedef.

        * typeck.c (common_type): If we're just returning one of our
        arguments, don't strip typedef types.
