> Hi all,
>
> this patch fixes an ICE recently reported by Andrew Benson. It does so
> by rejecting polymorphic arguments to the C_F_POINTER intrinsic. For
> discussion and standard references, please refer to the PR and today's
> email thread.
>
> Apart from fixing this PR, the patch modifies two other error messages
> related to C_F_POINTER (adding the name of the formal arg in the
> message and applying correct Fortran terminology through the
> replacement 'parameter' -> 'argument'). It also fixes the grammar in
> the documentation of C_F_POINTER.
>
> Regtested on x86_64-unknown-linux-gnu. Ok for trunk?
>
> Cheers,
