Bad type mismatch in ADDR_EXPR from cp/class.c:build_vtbl_initializer

[Richard Guenther]

If the following ever escapes the C++ frontend (who knows...)

    /* Take the address of the function, considering it to be of an
       appropriate generic type.  */
    init = build1 (ADDR_EXPR, vfunc_ptr_type_node, fn);

it'll be not nice.

(gdb) call debug_tree(t)
 <addr_expr 0x401f8060
    type <pointer_type 0x401b8a20 __vtbl_ptr_type
        type <function_type 0x401b89b4 type <integer_type 0x4014957c int>
            QI
       ....
    constant invariant
    arg 0 <function_decl 0x401f6a8c __comp_dtor
        type <method_type 0x401e2d14 type <void_type 0x401589b4 void>
            QI size <integer_cst 0x401411f8 8> unit size <integer_cst
0x40141210 1>
       ....


does it escape?  Would using convert on the ADDR_EXPR of the correct
type to vfunc_ptr_type_node work?

Thanks,
Richard.
