problem: H5Pset_istore_k(fcpl_id, ik) fails

see link to github example
HDF5 Version: 1.10.6

documentation suggest ik=65536 as max value, whereas library accepts only ik < 16384+1

int main() {
	char name[1024];
	hid_t fcpl_id, fd_id;
	herr_t err;
	unsigned ik;
	//unsigned max = 16384+1;
	unsigned max = 65536;
	for(unsigned i=32; i < max; i*=2) {
		sprintf(name, "name_%i.h5", i);
		fcpl_id =  H5Pcreate(H5P_FILE_CREATE);
		err = H5Pset_istore_k(fcpl_id, i);
		fd_id = H5Fcreate( name, H5F_ACC_TRUNC, fcpl_id, H5P_DEFAULT );
		H5Pget_istore_k(fcpl_id, &ik );
		printf("results: %i - %i = %i ", i, ik, i - ik);

		H5Pclose(fcpl_id);
		H5Fclose(fd_id);
	}
}
