     Unable to find Mach task port for process-id 19495: (os/kern)

This is macOS, where one cannot use GDB without some jumping through
hoops, sigh.

It's not too bad, IMHO.  Here are the instructions from etc/DEBUG:

    Running GDB on macOS sometimes brings an error message like this:

      Unable to find Mach task port for process-id NNN: (os/kern) failure (0x5).

    To overcome this, search the Internet for the phrase "Unable to find
    Mach task port for process-id", and you will find detailed
    instructions to follow.

Best regards,
