--- Comment #1 from Gerhard Steinmetz <gerhard.steinmetz.fortran@t-online.de> ---
Whereas :


$ cat z3.f90
program p
   integer, allocatable :: z(:)[:,:]
   allocate (z(1::2)[2,*])
end

$ gfortran-6 -fcoarray=single z3.f90
z3.f90:3:13:

    allocate (z(1::2)[2,*])
             1
Error: Bad array specification in ALLOCATE statement at (1)
