It seems like the combination of memory allocated with stdc's alloca() function
and synchronized(this) [as shown in the outcommented code in the paste] cause
an internal error in eh.c.

Neither a D-way copy ..

    synchronized (this)
        list[] = queueList;

..nor a memcpy..

    synchronized (this)
        memcpy (list.ptr, queueList.ptr, len * (QueueFile*).sizeof);

fixed this error.

It has been worked around via creating a synchronized copy method to perform
the same action.
