I am not sure if this a language, compiler, or library issue but when you call
spawn without passing all the parameters required by the fn it can either
segfault if you are lucky or worst yet have an unpredictable behavior.

For example the following code will compile and execute:

import std.concurrency;

void main()
{
   spawn(&fun);
}

void fun(int i) {}

My intuition is that the code above should not compile.
