I ran into this problem with threads. You can't just take a pointer to a
thread (ie &Thread.getThis). You have to use a cast(void*) for it to work.
I put the following print statement where I created the thread and in the
created thread:

    writefln("Thread %X is%s the main thread.", cast(void*)Thread.getThis,
              thread_isMainThread ? "" : "n't");

This worked, otherwise using '&' to get the pointer gave the same address.
