Assertion "INFO_CEXPRS (arg_info) == NULL"

Got this cryptic error whilst trying to extend the functionality of the Structures library. Only fails with -check c enabled.

module StructuresPlus;

import Structures: all;

export all; 

// inline complex * (complex X1, double X2)
// {
//   return((complex)[((double[2])X1)[[0]] ScalarArith::* X2,
//                     ((double[2])X1)[[1]] ScalarArith::* X2]);
// }

// inline complex * (double X1, complex X2)
// {
//   return((complex)[((double[2])X2)[[0]] ScalarArith::* X1,
//                     ((double[2])X2)[[1]] ScalarArith::* X1]);
// }
