TC problem with conditionals

The following program

int main()
{
    bodies = [1,2,3,4,5,6,7];

    accs = {[i] -> {[j] -> (_eq_SxS_(i,j) ? _sel_VxA_([i], bodies) : _sel_VxA_([j], bodies)) } };

    return(0);
}

when compiled with -noprelude yields:

./bodies.sac 5 error: Identifier '_hce_23` used without previous definition
./bodies.sac 5 error: Identifier '_hce_22` used without previous definition
./bodies.sac 5 error: Identifier '_hce_25` used without previous definition
./bodies.sac 5 error: Identifier '_hce_24` used without previous definition
compilation failed while Converting to static single assignment form, 4 error(s).
