--- Comment #5 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
An additional point. The called routine has

    pure function fpdbacksolve(x, S) result(Uix)

        real, dimension(3) ::  Uix

... and so on. This _requires_ Uix to be contiguous in memory,
so we need to call the internal pack routine.

This is something we cannot change easily. So, the workaround:

Use the appropriate memory layout in your Fortran programs.
