Is there an existing issue on issue.dlang.org? If not can you

I think that's a another bug related to init values.

I cannot find a way to actually modify immutable memory with
it...
a.d:
class C {
int a;
this(int a) {
this.a = a;
}
}
struct S {
int x;
C elem = new C(42);
~this() {
import std.stdio;
writeln("mutable ~this()");
x = 1;
elem.a = 123;
struct S {
int x;
~this() {
import std.stdio;
writeln("mutable ~this()");
x = 1;
}
}
void main() {
const(S) s1;
immutable(S) s2;
}
Prints:
mutable ~this()
mutable ~this()
This looks very wrong,
