[Bug libfortran/27895] problem with SPREAD and zero-sized arrays

[fxcoudert at gcc dot gnu dot org]

CSHIFT has the same problem:

$ cat zero_cshift.f90
  real :: tempn(1)
  tempn = 2.0 
  print *, cshift(tempn(2:),shift=1)
  end
$ gfortran zero_cshift.f90 && ./a.out
Floating point exception

I believe the following functions may not be safe: EOSHIFT, PACK, RESHAPE,
TRANSPOSE, UNPACK (and of course, SPREAD and CSHIFT).
