The following code compiles, but the program hangs (because the message is not
received by foo()). Without wrapping array into struct everything works. If
immutable(int[]) is changed to immutable(int)[] -- also works.

import std.concurrency;

struct A {
    immutable(int[]) a;
}

void foo(Tid tid) {
    receive(
       (A a) {
           send(tid, true);
       });
}

void main() {
    Tid tid = spawn(&foo, thisTid);
    immutable(int[]) a = [1];
    send(tid, A(a));
    receiveOnly!bool();
}

I would like to add my own program to this issue, which also hangs, most likely due to the same reason. If you remove ANY of the three members of the struct (and edit the message accordingly), the program passes normally. Only with all three struct members, it hangs:

import std.stdio;
import std.concurrency;

struct message_t {
  string str;
  int num;
  immutable(int)[] vec;
}

void func(Tid caller) {
  auto msg = message_t("foo", 42, [1, 2, 3]);
  caller.send(msg);
}

void main() {
  spawn(&func, thisTid);
  auto msg = receiveOnly!(message_t);
  writeln("received: ", msg);
}
