There recently was a bug report for GDC/ARM regarding this. As variants max
size is determined by creal which is only 16 bytes on most non-x86
architectures this error already happens with structs > 16 bytes on these
architectures.

Another test case with different error message:
---------
struct Big
{
    int[10] a;
}

import std.concurrency, std.variant, core.thread;

void loop()
{
    while(true)
    {
        Thread.sleep(seconds(10));
    }
}

void main()
{
    auto x = spawn(&loop);
    x.send(Big());
}

target must be non-null
