Confirmed; that's a bug all right.
AFAICT gdb doesn't have existing machinery to allow for undefined
pieces of a value. Perhaps one way to do this would be to add
a new field to struct value, which would be a bitmap tracking which
bits are known to be valid. Then, things like field lookups could
preserve this.
