Responsible-Changed-Why:
    Jason, the code where we abort comes from this patch:
    
    revision 1.131
    date: 2003/01/03 20:04:37;  author: jason;  state: Exp;  lines: +15 -1
            * fold-const.c (fold) [COND_EXPR]: Avoid NOP_EXPRs better.
    
            * integrate.c (copy_decl_for_inlining): Don't clear the rtl for
            static/external decls.
    cp/
            * call.c (build_conditional_expr): Stabilize lvalues properly.
            * cvt.c (ocp_convert): Don't build NOP_EXPRs of class type.
            * tree.c (lvalue_p_1): Don't allow sloppy NOP_EXPRs as lvalues.
            Don't allow CALL_EXPR or VA_ARG_EXPR, either.
    
            * call.c (convert_like_real): Call decl_constant_value for an
            IDENTITY_CONV even if there are no more conversions.
    
            * cvt.c (build_up_reference): Don't push unnamed temps.
    
            * decl2.c (do_namespace_alias): Namespace aliases are DECL_EXTERNAL.
    
            * dump.c (cp_dump_tree): Don't try to dump class-specific fields
            for a backend struct.
    
            * except.c (wrap_cleanups_r, build_throw): Make
            MUST_NOT_THROW_EXPRs void.
            * init.c (expand_default_init): Update to handle MUST_NOT_THROW_EXPR.
    
            * init.c (build_vec_delete_1): Pre-evaluate the base address.
    
            * init.c (get_temp_regvar): Simplify logic.
    
            * tree.c (cp_copy_res_decl_for_inlining): Only do debug tweaks if
            our replacement is a decl.
    
    I don't know whether this patch is actually responsible,
    but would you mind taking a look at this?
    
    Thanks
      W.
