[Bug fortran/28154] New: SPREAD (and friends) on unallocated arrays

[fxcoudert at gcc dot gnu dot org]

This is not a bug (I don't think the code is legal), but surely we could do
better than this:

$ cat zero_spread_2.f90 
  real,allocatable :: bar(:,:),foo(:)
  allocate(foo(0))
  bar = spread(foo,dim=1,ncopies=1)
  print *, allocated(bar)
  end
$ gfortran zero_spread_2.f90 && ./a.out
 T

Same goes for most of the transformational intrinsics.
libgfortran/intrinsic/spread_generic.c says:
  /* The front end has signalled that we need to populate the return array
descriptor.  */

We should really find another way of signaling this to the library (additional
argument?) so that we can perform some checking.
