I did not look it up but I expected the standard probably says something like
that, this is also why clang matches the gcc behavior. But GDB could try to
be more helpful displaying the data. For example DWARF could have the pointer
there at its type for sizeof and similar but additionally there could be some
new GNU attribute for printing the data.
Just I did not file it as I think C++ is more appropriate for such (or all)
cases where it already just works.
