          Issue ID: 15004
           Summary: std.concurrency fails to compile when sending static
                    array larger 32 byte
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1

Sending a static array larger than 32 Byte fails with the error (dmd 2.068,
same with 2.066 based ldc, so probably no recent regression):
dmd/phobos/std/variant.d(633): Error: new can only create structs, dynamic
arrays or class objects, not int[9]'s
dmd/phobos/std/variant.d(344): Error: new can only create structs, dynamic
arrays or class objects, not int[9]'s
[...]

I tested this string[n], int[n] and byte[n] - if the array is 32 Byte or
smaller, it works fine.

As the limit is the same, this is perhaps related to
https://issues.dlang.org/show_bug.cgi?id=10740 (although the error message is
different)

Test programm:

import std.concurrency;
import std.stdio;

void fun() {
    receive((byte[33] data) { writeln(data);});
}

void main() {
    byte[33] data;
    pragma(msg, data.sizeof);
    auto tid = spawn(&fun);
    send(tid, data);
}
