--- Comment #4 from Rainer Schuetze <r.sagitario at gmx.de> ---
You get the same result without default parameters, too:

///////////// test.d /////////////
import mod;

void main()
{
    fun(1, 10);
    fun(2, 10);
    fun(3, 10);
    fun(4, 10);
}
////////////// mod.d /////////////
void fun(int n, int defParam)
{
    assert(n != 4);
}
//////////////////////////////////


The problem seems to be that the backend always performs common sub expression
elimination, mapping all instances of "10" to the same expression instance and
then emitting its location.

I suspect this exists since forever, but I haven't tried older versions yet.
