By doing that, you are creating a local variable called
Vhome_directory that shadows the global one.  That's definitely not
what should happen.

Try changing it to

  Vhome_directory = hd ? string (hd) : string ("I have no home!");

If that fails to compile, do it like this instead:

  if (hd)
    Vhome_directory = string (hd);
  else
    Vhome_directory = string ("I have no home!");

There may be other places where you need to make similar changes.  Can
you please let me know where, so I can change my sources?

I think this problem is probably a bug in the compiler you are using,
but I'm willing to modify the Octave sources to work around the bug.

Thanks,
