Details:

__debug_octave__ uses the following to choose the command
to execute depending on whether it is running on macos, windows
or some other unix


 if (nargin == 0)
    status = system ("gdb --version");
    if (status != 0)
      error ("unable to execute gdb");
    endif
    if (isunix ())
      command_string = "x-terminal-emulator -e gdb -p %d";
    elseif (ispc ())
      command_string = "start gdb -p %d";
    elseif (ismac ())
      command_string = "osascript -e 'tell application \"Terminal\" to do
script \"lldb -p %d\"'";
    else
      error ("unknown system -- unable to determine how to start debugger");
    endif
  endif


unfortunately 

* gdb is not available by default on the mac so it should not be invoked
unconditionally before the "if" block

* "isunix" returns true on the mac so the "elseif (ismac ())" part of the code
is never executed.
