    Fortran: Fix double free on polymorphic array dummy argument [PR119349]

    Calling elemental routines with polymorphic formals leads to generation
    of a temporary polymorphic variable and code for its deallocation.
    Sourcing this element from an array constructor the latter now is
    prevented from generating a second deallocation.

            PR fortran/119349

    gcc/fortran/ChangeLog:

            * trans-expr.cc (gfc_conv_procedure_call): Prevent deallocation
            of array temporary for polymorphic temporary argument.

    gcc/testsuite/ChangeLog:

            * gfortran.dg/class_79.f90: New test.
