[Bug fortran/61275] Invalid initialization expression for ALLOCATABLE component in structure constructor at (1)

--- Comment #6 from Antony Lewis <antony at cosmologist dot info> ---
Not sure about that - 7.1.12 of 2008 is about constants, but in the example the
type instance is not a constant? The example is fine in ifort (and used in
cosmomc?).
