One test in data.cc crashes Octave 3.1.51

[Thomas Treichl]

Hi,

I have still some more problems after compiling 3.1.51 for PPC (but overall just 
7 test failures). One special test in data.cc crashes Octave, I have found out 
the source where it appears (data.cc, line 1064):

   %!assert(log2(complex(0,Inf)), Inf + log2(i));

I split the commands and found out more:

   octave:1> A = Inf
   A = Inf
   octave:2> B = log2(i)
   B =  0.00000 + 2.26618i
   octave:3> A+B
   panic: Segmentation fault -- stopping myself...
   ans = Inf + attempting to save variables to `octave-core'...
   save to `octave-core' complete
   Segmentation fault

And I don't have any idea where to go from here looking for this bug. My second 
test was:

   octave:1> complex(0,Inf)
   ans = 0 + Infi
   octave:2> log2(complex(0,Inf))
   ans = NaN - NaNi

Regards,
