        * gimplify.c (gimplify_decl_expr): Call gimplify_type_sizes
        on variable sizes types if a decl is a pointer to a VLA.
        (gimplify_type_sizes): Handle POINTER_TYPE and REFERENCE_TYPE.
        Call gimplify_type_sizes on aggregate fields.  Prevent infinite
        recursion.
        
        * gcc.dg/20050527-1.c: New test.
