--- 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.
