This fails for me in a DLL:
auto tid = spawn(&func);

If I print out the tid, I find that its message box is null.
This is odd, since according the code in std.concurrency
there's nothing weird about how it gets a message box, it's
just `auto spawnTid = Tid(new MessageBox);`. So... `new` is
returning null???
The really weird thing is that a thread is spawned and func
starts executing. I just can't send it any messages without
crashing.

If you suspect `new` of returning null, a GC issue seems
likely. Is your DLL linked statically against druntime, thus
having its own GC? Or are you using a shared druntime (and thus
GC) across multiple binaries?
Whatever's default on Windows 32-bit. The thing is, all other
uses of GC allocations in the same DLL work as expected.
