Thanks, but I tried that too and couldn't get it to work.

I added the following:

extern(C) handler()
{
     synchronized // needed here to avoid the GC to collect while attaching  
thread?
     {
         if(!Thread.getThis()) // thread unknown to D
         {
             thread_attachThis();
             assert(Thread.getThis()); // now D knows about it
         }
     }
     GC.collect(); // still segfaults
}

Actually, using attachThis segfaults GC.collect() outside the thread  
handling code too.
