--- Comment #1 from Ethan Gutmann <gutmann at ucar dot edu> ---
I see this same problem in gcc 7.1.0. Note that with -fcoarray=single there
are no errors.
$ gfortran --version
GNU Fortran (GCC) 7.1.0
$ gfortran -fcoarray=single -c allocatable-component-of-dt-coarray.f90
$ gfortran -fcoarray=lib -c allocatable-component-of-dt-coarray.f90
