           Version: D2
          Hardware: x86_64
                OS: Linux

          Severity: regression
          Priority: P1

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

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

Test command: dmd -g test.d mod.d ; ./test 2>&1 | grep _Dmain
Output with 2.072.2: test.d:8 _Dmain [0x427dc7]
Output with 2.073.0: test.d:5 _Dmain [0x427d37]

The correct line number is 8, not 5.
