            Bug ID: 18280
           Summary: pointer values returned from pretty-printers are not
                    printed
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: python

The pretty-printer is returning an int * value but gdb isn't printing it.

The problem seems to be in c_val_print, case TYPE_CODE_PTR
and print_address_demangle.

If we end up here:

int
print_address_demangle (const struct value_print_options *opts,
                        struct gdbarch *gdbarch, CORE_ADDR addr,
                        struct ui_file *stream, int do_demangle)
{
  if (opts->addressprint)
    {
      fputs_filtered (paddress (gdbarch, addr), stream);
      print_address_symbolic (gdbarch, addr, stream, do_demangle, " ");
    }
  else
    {
=>    return print_address_symbolic (gdbarch, addr, stream, do_demangle, "");
    }
  return 1;
}

nothing gets printed.
