I'd have to guess a bug in the egcs snapshot you are using.  Have you
tried a more recent snapshot since then?

If you think the bug is really in Octave, can you please try to debug
it?  I believe the lines that the error messages refer to are

  if (WIFEXITED (status))
    status = WEXITSTATUS (status);
  else
    status = 127;

What are the definitions of WIFEXITED and WEXITSTATUS on your system?
