debug import std.stdio;
struct A {
public:
int id;
this(int id) {
debug writeln("CTor A with ", id);
this.id = id;
}
debug ~this() {
writeln("DTor A with ", id);
}
}
----
bar.d
----
import foo;
void test(A a) {
a.id++;
}
void main() {
test(A(42));
A a = A(23);
test(a);
}

Usage:
C:\Users\Besitzer\Desktop>dmd -lib foo.d

====
Without -debug or with 'debug' _in_ the DTor (before writeln)
instead before the DTor works fine.
