            Bug ID: 64945
           Summary: Structure constructors and non-NULL-data-targets and
                    polymorphic pointer components
           Product: gcc

Follow up to PR64757 and https://gcc.gnu.org/ml/fortran/2015-02/msg00022.html

The patch for PR64757 handles polymorphic allocatable components with structure
constructors. [Somewhat related PR50438, PR39988, PR49213]

I am pretty sure, we need to do likewise with pointer components (class =>
class but also class <-> type). (See also raw patch at PR39988, which I haven't
checked what exactly it fixes.)
