--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The code to print the target object is pretty funky, but it seems like it isn't
even being used here; the output is just the raw output you'd get without a
pretty printer.

So why isn't GDB using the StdExpAnyPrinter for the type
std::experimental::fundamentals_v1::any? Hmm.

    libstdc++: Fix std::any pretty printer [PR 68735]

    This fixes errors seen on powerpc64 (big endian only) due to the
    printers for std::any and std::experimental::any being unable to find
    the manager function.

            * python/libstdcxx/v6/printers.py (function_pointer_to_name):
            New helper function to get the name of a function from its
            address.
            (StdExpAnyPrinter.__init__): Use it.
