------- Comment #2 from burnus at gcc dot gnu dot org  2009-01-12 16:59 -------
For the diagnostics: I think it works, but we are checking in case of
C_LOC(Type%Comp)  the symbol Type instead of Comp. Assume that Type is a
pointer and Comp is not then "gfc_is_data_pointer()" returns true for Type%Comp
even though it is not a pointer (Type is a pointer, Type%Comp is the component
of the target to which Type points). But somehow also the is_scalar_expr_ptr
check and the args_sym->attr.dimension check point do something wrong.

For rejects valid: Make "Type" a pointer and Type%Comp an array.

The ICE itself is fixed by the following patch:
