I have downloaded the 0.79 binary version of Octave from 
  ftp.che.utexas.edu:/pub/octave/sparc-sun-sunos4.1.2

I have got the following bugs:

1)
octave:1> implicit_str_to_num_ok = 1
implicit_str_to_num_ok = 1
octave:2> setstr(abs('a'))
ans = aý0
octave:3> 

2)
octave:1> implicit_str_to_num_ok = 1
implicit_str_to_num_ok = 1
octave:2> lf=0
lf = 0
octave:3> b=setstr(lf)
b = 
octave:4> abs(b)
Illegal instruction

3)
octave:1> implicit_str_to_num_ok = 1
implicit_str_to_num_ok = 1
octave:2> a=[0 0]
a =

  0  0

octave:3> b=setstr(a)
b = 
octave:4> length(b)
ans = 1
octave:5> b'
panic: impossible state reached in file `tree-const.cc' at line 1030
error: caught SIGIOT -- stopping myself...
