reproducer

This issue appears to be present in gfortran-9,10,11. A minimal reproducer =
is
provided.

I have an abstract base class, from which one class is derived which itself=
 is
further derived one more time. When allocating an array of the most-derived
type, for some reason the finalizer of the intermediate class is called. Th=
is
does not happen with ifort or xlf, and I don't think it should happen.

output:

 allocating
 solver_gpu_final    <-- this being called is a bug (IMHO)
 allocating done
 solver_sparse_gpu_final
 solver_sparse_gpu_final
 solver_gpu_final
 solver_gpu_final=
